Computational Fluid Dynamics (CFD) is used in almost all aspects of the aerospace industry today. It involves calculating flow interactions between solid boundaries, such as flat plates or airfoils, and liquid or gaseous mediums. The CFD code currently being used is a simple computer code algorithm consisting of time marching through millions of calculations and numerous iterations. This report involves a comparison of this current code and a newer version of the same code which involves periodically retrieving a set of solver coefficients from a database of settings optimized for fast converg...
Computational Fluid Dynamics (CFD) is used in almost all aspects of the aerospace industry today. It involves calculating flow interactions between solid boundaries, such as flat plates or airfoils, and liquid or gaseous mediums. The CFD code currently being used is a simple computer code algorithm consisting of time marching through millions of calculations and numerous iterations. This report involves a comparison of this current code and a newer version of the same code which involves periodically retrieving a set of solver coefficients from a database of settings optimized for fast convergence. This process enables the computer to solve these calculations using the optimum variables and leads to a shorter computational time frame. Considering how a full CFD run through of a fully assembled aircraft can take weeks, any time saved leads to a reduced bottom line and a faster design and build time for the aerospace industry.
