Substantial Body

This article is aimed at relating a certain substantial body of established material concerning wave loading on offshore structures to fundamental principles of mechanics of solids and of fluids and to important results by G. I. Taylor (1928a,b). The object is to make some key parts within a rather specialised field accessible to the general fluid-mechanics reader.The article is concerned primarily to develop the ideas which validate a separation of hydrodynamic loadings into vortex-flow forces and potential-flow forces; and to clarify, as Taylor (1928b) first did, the major role played by components of the potential-flow forces which are of the second order in the amplitude of ambient velocity fluctuations. Recent methods for calculating these forces have proved increasingly important for modes of motion of structures (such as tension-leg platforms) of very low natural frequency.

During pressing using high speed, the material is stressed to the limit of its mechanical properties. And this generates problems during production. For this reason, opens debate on the factors previously neglected, such as the strain rate. For determining the effect of strain rate on the pressing process has been designed to CTU, Faculty of Mechanical Engineering, Institute of Manufacturing Technology, equipment for monitoring the behaviour of the material at different strain rates. The article describes the creation of testing methodologies material behaviour using this device.

The typical fluid mechanics introduction in mechanical engineering covers basic fluid statics, forces on submerged bodies, control volumes, continuity, conservation of momentum, conservation of energy, Reynolds' transport theorem, internal and external flows. Students often struggle with the basic concepts and how they might apply to a real system.In the winter of 2015, a new set of open-ended labs were created for  mechanical engineering students. Teams of 3 or 4 students in a third-year class of 110 were each given a small engine, and removed the carburetors. The series of labs had them discover some of the principles within the  small carburetor from a single-cylinder 4-stroke gasoline engine. Students were asked to explore and explain how the carburetor worked, and then progressed through a set of hands-on labs culminating with a design modification and performance measurement of a real carburetor. At each stage, the students applied principles of fluid statics, control volumes,  internal flow losses, and external flow drag to the physical device.The paper will describe the specific activities, and track the evolution of refinements to the experience through three implementations of the same course by three different instructors. Student feedback and measured evidence of learning will be reported to help justify the evolution of the  activity. The scalability of the activity will be discussed.

This study describes a model for developing a thermo/fluids curriculum in a new mechanical engineering program. Hands-on experience and applied engineering research are the center of this development. The efforts in creating undergraduate, elective, and graduate level courses and laboratories in the fundamental topics of thermodynamics, fluid mechanics, and heat transfer are reviewed and explained in detail. A dual approach has been taken in developing the curriculum, so that both undergraduate and graduate students can utilize the facility in their research activities. This development has been revised and optimized since its initiation in 2005, and it has successfully been accredited by ABET. The good results obtained from this model can be used in developing mechanical engineering programs, especially for smaller-sized institutions.

Definition Of

As a result of mechanical engineering curriculum revision at the United States Military Academy at West Point, separate courses in thermodynamics and fluid mechanics were integrated into a two-course sequence, Thermal-fluid Systems I and II, in academic year 2005–2006. After four years of instruction using available text books from publishers, the mechanical engineering faculty developed a text tailored specifically to the integrated two-course sequence. The experience in writing a text that integrates concepts in thermodynamics and fluid mechanics highlights the need for consistency between the two disciplines. Issues identified include logical organization of topics, selection of appropriate variables, consistent use of sign convention throughout all topics, recognition of various forms of the same fundamental principle, and definition of performance parameters. This paper explores these issues and how they were addressed for integrated instruction of thermodynamics and fluid mechanics.

Abstract Experiences related to a new sophomore level course, “Introduction to Thermal Fluid Engineering,” are described. Several hundred students have taken the course and are currently enrolled in the follow-on courses in thermodynamics, fluid mechanics, and heat transfer. The introductory course is structured as a two-hour per week lecture with a laboratory that meets three times during the semester. Although thermodynamics, fluid mechanics, and heat transfer subjects are introduced sequentially during the course, the overlap and inter-relationships between topics are emphasized. It has been beneficial both for students and the faculty teaching the course to see the bigger picture of the three courses as a whole rather than as separate topics. The open laboratories are manned by a graduate student or senior who guides the students through hands-on experiments. Each of the three simple experiments is designed to illustrate important principles and reinforce the computational skills of the students. A web site has been established to help guide the students in preparing the written portion of the laboratory report. Team teaching of some sections has been tried and compared to the standard one teacher per section approach. Feedback from the students indicated a surprising acceptance of having several teachers for a course when they were well coordinated. One advantage mentioned by the students was to introduce them to more of the mechanical engineering faculty early in their studies. Because this is the first course requiring engineering analysis taught by the mechanical engineering faculty, it provides the opportunity to direct them in their problem solving and organizational skills that will be useful throughout the rest of their courses. Student evaluations are included as part of the results presented.
