Sample Questions

Question 1
In CFD post-processing, what does a streamline represent?
A line tangent to the velocity vector field at every point at a given instant
The path traced by a fluid particle over time
A line connecting points of equal pressure in the flow domain
A contour of constant vorticity magnitude
Question 2
Which metric is used to assess spatial discretization error in CFD by comparing solutions on systematically refined grids?
Courant-Friedrichs-Lewy (CFL) number
Grid Convergence Index (GCI)
Reynolds Averaging Error (RAE)
Kolmogorov length scale ratio
Question 3
What is the primary purpose of a Q-criterion isosurface in CFD post-processing?
To visualize regions of high pressure gradient
To identify and visualize vortical structures in the flow
To show areas where the mesh quality is poor
To mark zones of flow separation from walls
Question 4
In verification and validation (V&V) of CFD, 'verification' specifically refers to:
Comparing CFD results against experimental data to assess physical accuracy
Ensuring the numerical algorithm correctly solves the governing equations
Checking that the mesh meets quality thresholds such as skewness and aspect ratio
Validating that the turbulence model is appropriate for the flow regime
Question 5
When monitoring residuals during a steady-state CFD simulation, which condition best indicates convergence?
Residuals exceed 1e-2 for all transport equations
Residuals plateau at a constant non-zero value and key monitor quantities stabilize
Residuals oscillate periodically with decreasing amplitude
Residuals drop to exactly zero for the continuity equation
