D2Q9 MRT lattice Boltzmann have been used to simulate fluid flow inside of a rectangular lid-driven cavity. Bounce back BC implements for 3 stable walls and Zou and He BC scheme performs for moving wall.

Here is a simple Simulink file to calculate the stiffness of hydraulic spring.The theory is explained in my book:M Galal Rabie, Fluid power Engineering, McGraw-Hill, NY, 2009, pp 235-237

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: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...

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...
