TechnoPro CFD Analyst Interview Questions and Answers

Turbulence models are used to predict the behavior of turbulent flows by simulating the effects of eddies and vortices.

• Turbulence models are based on the Navier-Stokes equations, which describe the motion of fluids.

• They use statistical methods to simulate the effects of turbulence on the flow.

• There are two main types of turbulence models: Reynolds-averaged Navier-Stokes (RANS) and Large Eddy Simulation (LES).

• RANS model...read more

Steady solver solves for a steady-state solution while transient solver solves for a time-dependent solution.

• Steady solver assumes that the solution does not change with time while transient solver considers the time-dependent behavior of the solution.

• Steady solver is faster and less computationally expensive than transient solver.

• Transient solver is required for problems that involve time-varying boundary conditions o...read more

Mesh independent study is a process of verifying the accuracy of simulation results by varying the mesh size.

• It involves running simulations with different mesh sizes

• The results are compared to determine if they converge to a consistent solution

• It helps to ensure that the simulation results are not dependent on the mesh size

• It is important for accurate and reliable CFD simulations

• Example: A CFD analyst may perform a me...read more
