Orbital Velocity Equation

We use the genetic algorithm (gatool) to determine the three parameters of the simple Antoine equation and the six parameters of the Modified Antoine Model. Predictions are in perfect agreement with experimental data of vapor pressure of ethanol versus temperature for a temperature range from...

The code computes the velocity profile for the vertical laminar flow of a Bingham fluid down a wall. As expected the profile is flat near the surface of the liquid film. In fact, we have a zero velocity gradient only when the shear stress is large enough (superior to tau0). This behaviour is...

A script to calculate the saturation vapor pressure (in Pascals) according to equation by Goff & Gratch (1946), as a function of temperature on Kelvin scale.

The velocity and shear stress versus radial position are obtained for the laminar flow of a power-law fluid in a pipe. Pipe radius and applied pressure gradients can be set by the user. If you choose a power-law exponent, n, equal to 1 then a Newtonian fluid is recovered. Dilatant and...

The Stellar Aberration 3D Model illustrates the phenomenon known as the aberration of starlight, first reported by James Bradley in 1729. Aberration occurs because light has a finite speed, and thus light from a star takes a finite amount of time to travel through the tube of a telescope. During...
