WebWhen can you assume incompressible flow? In fluid dynamics, a flow is considered incompressible if the divergence of the flow velocity is zero. Are all fluids compressible? … WebA flow is said to be incompressible if the density of a fluid element does not change during its motion. It is a property of the flow and not of the fluid. The rate of change of density of a material fluid element is given by the material derivative. Hence the flow is incompressible if the divergence of the velocity field is identically zero.
