In the presented study, a thermal analysis of a lithium-ion battery was carried. The battery consists of 6 Series 2 parallel, 12 lithium-ion (NCA 18650) batteries. Liquid water was used as a refrigerant in the thermal analysis of the battery. After designing in SOLIDWORKS computer-aided design program, performance of the battery module was investigated with the help of SIEMENS FloEFD program which is a computational fluid dynamics program. The simulations were performed under steady-state conditions by using the k-epsilon turbulence model. The results bring out that the highest temperatures were occurred at the busbars and the liquid cooled batteries can operate efficiently at a temperature of 27-28°C.

The following paper presents an overview of the Prometheus design system and its applications to gas turbine combustor design. Unlike a traditional “optimizer-centric” method, Prometheus aims to reduce both the level of workflow complexity and rework by taking a more “geometry-centric” approach to design optimization by shifting the control of script generation away from the optimization program to the computer aided design (CAD) package. Prometheus therefore enables significant geometry changes to be automatically reflected in all subsequent scripts necessary for the analysis of a combustor. Prometheus’ current capabilities include automatic fluid volume generation and aero-thermal and thermo-acoustic network generation as well as automatic mesh and computational fluid dynamics (CFD) script generation.

Abstract: The objective of the present study is to design and analyze semi-tangential ogive bullets using simulatation software such as Computer-aided design & Computational Fluid Dynamics (CFD). It is observed that been a quite steady increase in the bullet research design in the past few decades. The nose section of ballistic bullet is the most important part of the design process. Hence design optimizations are achieved by adjusting the bullet's form to improve precision and stability by reducing its drag force. CFD is the study used to verify the findings. Since provides most accurate results. It is observed that present study optimizes the behavior of the at M= 2.5. This present work shows the flow of air around the bullet surface providing pressure & velocity contours at every segment. The Various parametric studies over bullet model are drag co-efficient, ballistic coefficient and turbulence viscosity are plotted’.
