In fluid dynamics, a flow is considered incompressible if the divergence of the flow velocity is zero. However, related formulations can sometimes be used, depending on the flow system being modelled. Some versions are described below: 1. Incompressible flow: . This can assume either constant density (strict incompressible) or varying density flow. The varying density set accepts solutions involving small perturbations in d… WebAn ellipse is moving through an incompressible fluid with a freestream velocity v 0 . If the fluid velocity (relative to a stationary ellipse) at a point on the top of the ellipse is v = 1.5 v 0 , what is the pressure coefficient at that location?
