For an unsteady, compressible flow field that is two-dimensional in the xy-plane and in which temperature and density variations are significant, how many unknowns are there? List the equations required to solve for these unknowns. (Note: Assume other flow properties like viscosity, thermal conductivity, etc., can be treated as constants.)
In a steady, two-dimensional flow field in the xyplane, the x-component of velocity is u = ax + by + cx2 where a, b, and c are constants with appropriate dimensions. Generate a general expression for velocity component ? such that the flow field is incompressible.
Converging duct flow is modeled by the steady, twodimensional velocity field V-›= (u, ? ) = (U0 + bx) i-›− byj-› where U0 is the horizontal speed at x = 0. Use the equation for volumetric strain rate to verify that this flow field is incompressible
