Computational Fluid Dynamics (CFD) branch of fluid mechanics It uses numerical analysis and data structures to analyze and solve problems involving fluid flow.

What can computational fluid dynamics be used for?

Computational Fluid Dynamics (CFD) is an engineering tool Used to simulate the action of thermal fluids in a system. Many industries use it in development work to analyze, optimize, and verify the performance of designs before expensive prototyping and physical testing.

What are the disadvantages of computational fluid dynamics models?

Disadvantages of using CFD for virtual experiments:

Errors may occur due to simple flow models or simplified boundary conditions. Uncertainty that may be caused by too few calculated valueseach cell, thus resulting in an interpolation error. Computation time may be extended for large models.
