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

Correct Answer:

A line tangent to the velocity vector field at every point at a given instant

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

Correct Answer:

Grid Convergence Index (GCI)

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

Correct Answer:

To identify and visualize vortical structures in the flow

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

Correct Answer:

Ensuring the numerical algorithm correctly solves the governing equations

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

Correct Answer:

Residuals plateau at a constant non-zero value and key monitor quantities stabilize
