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 ...

New analysis of two recently translated papers, first published in the 1850s, assesses the early methods used by Alfred Clebsch to describe the flow of incompressible fluids, and explores their impact ...

The interaction between an incompressible viscous fluid and an immersed rigid body presents a rich tapestry of physical phenomena and mathematical challenges. At its core, the problem involves the ...

Turbomachines for propulsion applications operate with many different working fluids and flow conditions. The flow may be incompressible, such as in the liquid hydrogen pump in a rocket engine, or may ...

Dealing with general problems in fluid mechanics, convection diffusion, and more, this is a complete, stand-alone reference on fluid mechanics applications of the FEM for mechanical, aeronautical, ...
