Standard time-marching compressible flow solvers used extensively in the aerospace industry cannot be applied incompressible flows, as the governing equations lack a time derivative in the continuity ...

Editor’s note: The Basics department this month is an excerpt from the ISA book Flow of Industrial Fluids – Theory and Equations by Raymond Mulley. Some material in this section may seem self-evident ...

Drew, an oceanography graduate student, writes: “This, on my leg, is the incompressible form of the conservation of mass equation in a fluid, also known as the continuity equation. When people ask ...

When a fluid is in motion, it must move in such a way that mass is conserved. To see how mass conservation places restrictions on the velocity field, consider the steady flow of fluid through a duct ...
