Question

Example: Irrotational Velocity and Pressure Fields Given: A steady, 2-D, incompressible velocity field is given by velocity components, u=2x+y v=x-2y We are ignoring units in this problem (the units of the constants are adjusted such that the velocity components have appropriate units). We also ignore gravitational effects. At the origin (x,y) = (0,0), P = P$_0$. To do: Generate expressions for the velocity potential function, the stream function, and the pressure field.

          Example: Irrotational Velocity and Pressure Fields
Given: A steady, 2-D, incompressible velocity field is given by velocity components,

Step 1

Step 1: To find the velocity potential function, we need to find a function φ(x, y) such that the velocity components u and v can be expressed as the partial derivatives of φ with respect to x and y, respectively. Show more…
