Aerospace Engineering Interview Question:

Can you please explain the difference between incompressible and compressible flows?

Submitted by: Muhammad

► Incompressible flows are the flows that have a constant density (?). Whereas, the compressible flows are those that consists of variable densities.
► The flows that exist are compressible in nature. Whereas, incompressible flows, doesn't exist in nature or are very rare.
► Incompressible flows are used to model aerodynamic problems without loosing any detrimental accuracy i.e. most problems that exist in hydrodynamics considers the density (?) = constant. Whereas, compressible flow is hardly used as a mathematical model to, represent the hydrodynamics.
► High speed flows are and must be treated as compressible, whereas incompressible flows are not considered for high speed flows.
