CFD Engineer Interview Questions and Answers for Freshers

CFD stands for Computational Fluid Dynamics. It is a branch of fluid mechanics that uses numerical analysis to solve and analyze problems related to fluid flow and heat transfer.

• CFD is important in designing and optimizing various engineering systems such as aircraft, automobiles, and power plants.

• It helps in predicting the behavior of fluids and their interaction with solid objects.

• CFD simulations can be used to optimize the design of products and reduce the need for physica...read more

Different viscous models in CFD include laminar, turbulent, and transitional models.

• Laminar model assumes flow is smooth and predictable, suitable for low Reynolds numbers.

• Turbulent model accounts for chaotic and unpredictable flow behavior, suitable for high Reynolds numbers.

• Transitional model combines aspects of both laminar and turbulent models for flows transitioning between the two.

• Examples include Spalart-Allmaras model for turbulence and SST k-omega model for transitio...read more
