Among the essential branches of fluid mechanics concerned with the use of numerical analysis and data structures to analyze and solve problems that involve fluid flows is the Computational fluid dynamics (CFD). I advise you to read my articles, you can find many specific examples of the use of this branch of fluid mechanics in the practice of the HVAC Applications.@

CFD is the numerical solutions of fluid dynamics problems.
