A tutorial from NASA on best practices in verification and validation of CFD solvers. ANSYS Fluent is a high end CFD that models flow, turbulence, and heat transfer in 3d. Incorporating advanced fuel spray models and high-fidelity fuel chemistry models, the company's FORTÉ CFD package boasts accurate results in hours—one to two orders of magnitude faster than current CFD tools, according to the company. This study first surveyed the recent development of turbulence modeling in computational fluid dynamics (CFD) and the applications in predicting indoor airflows. The modeling and meshing of turbine rotor is performed in ICEM-CFD. Moreover, the difference in meshing schemes between fixed pitch and variable pitch is also mentioned. The target audience for this course is practicing engineers who wish to learn more about how to choose and apply effective turbulence modeling in their CFD analysis. It allows engineers to focus on other problems that combine CFD and combustion simulation, such as turbulence models, according to Rosenthal. Mesh motion option is employed for variable pitch turbine. The basic structure of a CFD code: Pre-processor, Solver and Post-processor, User-defined-subroutines, Solution to some basic problems in heat transfer and fluid flow. Imagine being able to take a 3d model of a sky diver (or an aircraft) and place it at different orientations and different poses.
