Fluid Retention

The electromagnetic torque motors are widely used in electrohydraulic servovalves. They serve to convert the control current into a proportional torque. For more details about the steady state and transient response calculation, please refer to my book:M Galal Rabie, Fluid Power Engineering,...

Stokesian Dynamics, a method developed by Brady and Bossis in the 80s, simulates the 3D motion of hydrodynamically interacting spheres at low Reynolds numbers. This program was originally written by Professor Ron Phillips during his PhD thesis at MIT in 1989. The code was adapted from Fortran 77...

This file illustrates the effect of a properly designed proportional integral controller on the performance of Electrohydraulic servoactuators. The description of construction, operation and mathematical modeling of the Electrohydraulic servoactuator and steps of design of the PI controller are...

The electrohydraulic servovalves are mostly multi-stage. They incorporate, mostly, a first stage which serves to convert the command current into a proportional pressure difference. For more details about the steady state and transient response calculation, please refer to my book:M Galal Rabie,...

A Kirchhoff elliptic vortex is a 2D elliptical region (or d-deDUpatchd-deDt) of uniform vorticity embedded in an inviscid, incompressible and irrotational fluid. G. Kirchhoff showed that these are exact solutions to the nonlinear Euler equations in 1876.Subsequently, A. E. H. Love analyzed the...

Five scripts that demonstrate some aspects of the dynamics of rotating reference frames:1) rotation.m shows a very simple 3-d trajectory from inertial and rotating reference frames.2) Coriolis.m simulates a 2-d trajectory in a rotating frame that omits the centrifugal force. This allows several...
