Lesson 29: Interview Questions and Tips Copy

If you go for any interviews related to CFD job, especially if you a beginner it is common that the interview panel will test your fundamental knowledge in CFD, fluid mechanics, heat transfer etc. In general the technical interview will have 30% weightage on your fundamentals, 30% on the domain knowledge (for example if you are going for a position of CFD Engineer for turbomachines, you need to have good knowledge in the field of turbomachines), 20% on Tools like Fluent, StarCCM etc and 20% on your technical presentation skills or other soft skills.

Note: This is a general pattern and will vary depending on companies and interviewers. Ultimately they want to recruit a knowledgeable and skilled Engineer. 

Some basic questions related to CFD which you must know:

CFD will help in solving complicated problems and also to reduce the cost as it can reduce experiments.  But it is not necessary for every fluid mechanics problems in the industry. Many problems can be solved with lot of approximations and simplifications using just pen and paper (for quick calculations). If that is not feasible then we must try to do a simplified CFD model ( a 2D case). If 2D doesnt work, then do a full 3D simulation with RANS turbulence models. If that also doesn’t serve then only we need to use complicated, time consuming and expensive LES approaches. 

Go to Lesson 5 to 6 and learn continuity, momentum and energy equations. Try to explain different terms in the equation as surface force, body force etc. Also try to explain the general form of governing equation, Lesson 7 and explain different terms as diffusion, convection etc. 

Whether it is steady flow or unsteady flow the governing equation for an incompressible flow is the same without the unsteady term. Because the density is always constant. Go to lesson 5 for clarity. 

Go to lesson 7 and understand how a general partial differential equation is classified as elliptic, parabolic, hyperbolic etc. The understanding will help is choosing the right CFD discretization approach and strategies to capture the physics. For more insights watch the lecture 7. 

This is the discretised form of partial differential equation after using FVM or FDM techniques. And we solve these equations and not the PDEs directly.
