CFD Simulation | Siemens

A CFD simulation involves the use of the fundamental laws of mechanics, governing equations of fluid dynamics and modeling to mathematically formulate a physical problem. Once formulated, computing resources use numerical methods to solve the equations using CFD software to obtain approximate solutions for the physical properties involved.

CFD simulations are based on the Navier-Stokes equations used to describe the temperature, pressure, velocity, and density of a moving fluid. The accuracy of CFD simulations depend on the fidelity of the model, approximations and assumptions used, experimental validation and the computing resources available. It is important to characterize the uncertainties and errors in the CFD simulation to use it as an effective tool in design and analysis.
