The use of the SINDA/FLUINT computer code (Reference 1) for solving convective cooling problems has proven to be a valuable design and analysis tool. SINDA/FLUINT is used to efficiently support design applications where thermal analysis involving both heat transfer and fluid flow are involved. The program allows for simplification of fluid modeling compared to older versions of SINDA where this could only be done through user-generated logic. Also, SINDA/FLUINT provides a faster and simpler analysis basis over more complex fluid dynamics software programs, which can be an advantage for certain design applications. This paper discusses the utilization and benefits of SINDA/FLUINT for examples of such designs.
