Question

Numerical panel methods are applicable for

• A. steady, incompressible and inviscid flows only
• B. unsteady, incompressible and inviscid flows
• C. steady, compressible and inviscid flows
• D. unsteady, compressible and inviscid flows

Hint:

Panel methods are ideal for aerodynamic analyses of aircraft at low speeds where compressibility effects can be neglected.

Answer 1

The Correct Option is A

Step 1: Define Numerical Panel Methods.
Numerical panel methods are a class of computational techniques used in fluid dynamics to solve boundary integral equations for flow fields around bodies. These methods typically assume potential flow, which implies incompressibility and inviscidity.
Step 2: Application Scope.
Panel methods are particularly effective for steady, incompressible, and inviscid flows where the flow can be assumed to be potential. These assumptions simplify the calculations significantly, making panel methods unsuitable for compressible or unsteady flows where these simplifications do not hold.
