Question 1: How does vortex generation affect the aerodynamic performance of a vehicle?

Which action should you take?

Choose only one option

Reduces drag

Stabilizes lift distribution

Improves fuel efficiency

Increases drag

Question 2: How does the Large Eddy Simulation (LES) turbulence model differ from Direct Numerical Simulation (DNS)?

Which action should you take?

Choose only one option

LES resolves all scales of turbulence

LES is limited to incompressible flows

LES uses filtering to resolve larger scales

LES is computationally more expensive

Question 3: How does vehicle ride height impact aerodynamic drag?

Which action should you take?

Choose only one option

Ride height has no impact on drag

Lower ride height reduces drag

Drag increases exponentially with ride height

Lower ride height increases drag

Question 4: What type of sensor is commonly used to measure pressure distribution during aerodynamic testing?

Which action should you take?

Choose only one option

Accelerometer

Pitot tube

Optical fiber sensors

Thermistor

Question 5: How do you determine the drag coefficient of a vehicle during wind tunnel testing?

Which action should you take?

Choose only one option

Measure lift force

Measure force components in the flow direction

Use computational fluid dynamics (CFD) exclusively

Calculate using surface roughness data

Question 6: How do vortex generators improve vehicle aerodynamic performance?

Which action should you take?

Choose only one option
