Casting integrity is essential for providing components that meet design criteria for strength and fatigue performance. As the leading method of manufacturing metal components in the rail industry, maintaining quality and consistency is a continuing struggle for car owners and builders. Internal shrinkage and voids due to insufficient metal flow are issues commonly found in casting molds which are not designed or utilized properly. Using casting simulation software, potential issues can be discovered upfront and robust mold designs can be created that offer a tolerance for the variance or variations in casting conditions that are present in the real world. Strato, Inc. has extensively studied the effectiveness of these simulations in foundries through advanced inspection techniques. It is evident that casting simulations can not only locate, but also explain shrinkage cavities and voids through material density plots and inspection of directional solidification via critical fraction solid time plots. This approach is markedly more efficient than the traditional trial and error method, where mold makers rely on experience and destructive testing to develop acceptable mold designs. With recent advances in simulation software, the labor and time-intensive ways of the past have been supplanted by a more scientific approach to the problem. Understanding the fluid dynamics and thermodynamics of the casting process provides a means of creating a stable, repeatable final product. This higher quality final product can be delivered faster to the customer and at a far less expense by identifying problem areas prior to the tooling and sampling processes. Case-studies explored by the Strato engineering team suggest that using this software decreases the fallout rate.

Abstract This work will demonstrate how the Energy Recovery Inc. (ERI) engineering team improved the efficiency of a multistage pump by about 10% at the first stage, which translated into a 3% increase in the overall multistage pump efficiency; according to a set of engineering calculations and review of the archived in-house test data for the legacy multistage pumps, it was hypothesized that the performance pain-point of the pump was inefficient performance of the first stage, due to the formation of a strong pre-swirl right before its inlet. The validity of this hypothesis then was confirmed via RANS CFD simulations of the flow field inside the inlet suction housing and pump impeller. Same CFD methodology was used to evaluate multiple engineering solutions to reduce the strength of the inflow pre-swirl by modifying the inlet suction housing geometry. The obtained RANS CFD solutions guided the engineering team towards the most promising hardware modification proposal. The proposed geometrical modification of the inlet suction housing was implemented and tested on different multistage pumps. All of the test results validated the obtained RANS CFD numerical solution. The state of the art in this successful performance improvement process was first the on-point hypothesis development based on fundamentals of engineering and archived test data. Second, the proper RANS CFD methodology development to model/confirm the initial hypothesis and vet all possible engineering solutions to maximize the multistage pump efficiently and accurately. This can be a great example for various relevant turbomachinery industrial applications.

Abstract Although Concurrent Engineering can offer substantial benefits, and hence many companies take a strong interest in the collaborative approach, it is not yet clear how it can best be implemented, particularly for a geographically distributed Concurrent Engineering team that may be using a disparate range of computer systems. The recent rise in the number connected to the Internet would offer the possibility of using Internet standards to allow for collaboration over the Internet. Central to the use of Internet standards for Concurrent Engineering is the key area of transmitting and viewing CAD and engineering information, and of communication between team members. This paper is concerned with addressing this issue and describes the how 3D CAD files can be viewed, and engineering information exchanged, by geographically distributed team members in an interactive manner using Internet standards. In particular this paper is concerned with the issue of storing STEP data so that it can be retrieved efficiently, how this data can be converted from STEP data to the Virtual Reality Modeling Language (VRML) to allow the product to be viewed in interactive 3-D on a wide number of platforms using the Internet, and is concerned with the issue of how team members can markup the VRML worlds, with other team members being able to examine the markup comments of others. An algorithm for converting STEP data to VRML is described and an overview of the implementation of this approach, in a system called CyberView, is given. The result of this is that users from disparate functions, on a wide variety of platforms, can view products in interactive 3-D through the Internet, can comment on aspects of the design, and can examine the markup comments of other team members on particular aspects of the design. Such an approach offers the promise of improved communication and hence for enhancing the product development process.

Casing Deformation

Abstract During the completion phase of an unconventional well in Turkey, casing deformation represented a challenge to the operator and Coiled Tubing (CT) service provider due to the potential loss of almost 70% of the horizontal section. The deformation obstructed the path to continue the milling the remaining plugs. The implementation of bicentric mills and Multi-Cycling Circulation Valve (MCCV) incorporated in the milling assembly allowed efficient recovery of the horizontal section. The tubing condition analysis done by the engineering team showed that symmetric mills would not be beneficial. Conformance tubing was not an option. Bicentric milling approach was deemed the most viable solution. This approach consists of using offset mills where rotation causes the cutting head to cover an area larger than the mill's frontal face. However, this approach could lead the CT pipe getting stuck due to big junk left. The use of a MCCV, limiting the number of milled plugs, and performing a fishing run between milling runs were key to the success of the bicentric milling approach. The Turkish well was completed with ten stages isolated by nine aluminum plugs. During the fracturing of stage seven, an abnormal pressure drop was observed while keeping the same pump rate, indicating possible casing damage. After all the stages were fractured, the CT proceeded to mill the plugs using a 4.63-in Outside Diameter (OD) mill. After three plugs were milled, an obstruction was detected, indicated by frequent aggressive motor stalls at the same depth. A tapered mill was run to perform a tubing conformance, and after several hours of unsuccessful penetration, the tool was recovered. At the surface, the tool showed signs of wear around 4.268 in. A 4.0-in OD mill was used to drift this section, and it passed free. An analysis of both the plug anatomy and the casing condition was done to determine the most viable solution. A 4-in OD bicentric mill was designed to pass across the restriction with an adjusted eccentricity to allow higher contact area. Three bicentric milling runs were made with the limit of a maximum of two plugs per run to avoid a CT stuck situation due to the larger cuttings as a result of the mill's asymmetry. The sparsity of information on using bicentric mills for plug milling required research into unpublished practices for such scenarios. This paper documents bicentric milling approach, the use of offset mills, and the mitigation measurements taken during this project to avoid a stuck situation due to large debris generated.

This chapter describes an exploratory, qualitative research project that investigated the work environment necessary for virtual teams to be creative. Nine different virtual teams, with a total of 36 virtual team members (33 of which completed the full study), participated in this study. Three teams were organizational consulting firms, two teams were educational consortiums, three teams were on-line service provider teams, and one team was a product design engineering team. One semi-structured, telephone interview was conducted with each participant. Team members also completed a background survey. Grounded theorizing was used to generate an in-depth understanding of the phenomena under investigation. Connection, defined as the elements that need to be in place for a team to develop and maintain identity and a sense of community, emerged as a key category important to the realization of creativity in virtual teams. Connection was further subdivided into task connection (made up of dedication/commitment, and goal clarity); and interpersonal connection (made up of information sharing, trust, and personal bond). Suggestions for how team designers, team leaders, or managers can establish and develop connection in their own virtual teams are offered.

This article focuses on requirement of soft skills for communicating across departments in an organization. Fortunately, laying the foundation for good working relationships with other departments is a learned skill as experienced by management consultants. It starts with evaluating the role of the engineering department in an enterprise and continues with learning how to best communicate with employees of all personalities and skill levels. One soft skill that is easily learned and honed over time is the ability to communicate clearly. Another tip is to treat the person making a request of you the way you would for an outside customer. If another customer request supersedes, explain that to the employee requesting your time. Always take the time to proofread an e-mail or instant message, or any other form of written communication. Always treat employees from other departments just as you would for those in your own engineering team.
