- laminar flow
- turbulent flow
- mixed flow
- None of these

A

CFD: Research Tool Quiz

MCQ. When mach number < 0.8, flow is in

- subsonic regime
- super sonic regime
- sonic regime
- hypersonic regime

A

Finite difference method Quiz

MCQ. Formula of backward differencing is

- Δhf(x) = f(x+h) - f(x)
- 2Δhf(x) = f(x+h) - f(x-h)
- Δhf(x) = f(x) - f(x+h)
- Δhf(x) = f(x+h) + f(x-h)

C

Finite difference method Quiz

MCQ. Formula of central differencing is

- Δhf(x) = f(x+h) - f(x)
- 2Δhf(x) = f(x+h) - f(x-h)
- Δhf(x) = f(x) - f(x+h)
- Δhf(x) = f(x+h) + f(x-h)

B

MCQ. Test used to check accuracy of solution is called

- grid independence test
- solution test
- optimal test
- aspect test
