Two Phase Flow Pressure Drop Calculation Using Homogeneous Equilibrium Model

Although two-phase flow is frequently encountered in various location of the process plants, there is no a general accepted and verified two-phase flow model that may be used to size lines for such conditions. An obvious example is condensate water return lines. The API method that used in this study is based on the homogeneous equilibrium flow assumption, that is, equal velocity and equal temp...

Barycentric coordinates computation in homogeneous coordinates

Homogeneous coordinates are often used in computer graphics and computer vision applications especially for the representation of geometric transformations. The homogeneous coordinates enable us to represent translation, rotation, scaling and projection operations in a unique way and handle them properly. Today’s graphics hardware based on GPU offers a very high computational power using pixel ...

A Kinematic Model of Wave Propagation

We present a purely kinematic model of wave propagation in an excitable medium, namely cardiac tissue. The kinematic model is constructed from a standard reaction-diffusion model, using asymptotic techniques to track the position and velocity of each propagating wave front and wave back. The kinematic model offers a substantial improvement in computational efficiency without sacrificing the abi...

Application of Kinematic Wave Cascading Plane to Irregular Watershed

Storm water management models using the kinematic wave (KW) approach require the conversion of a natural watershed to its equivalent rectangular cascading plane. A KW cascading plane is specified by the plane’s area, width and slope. Without on-site calibration, there is no guidance how to translate the irregularity of the natural watershed into a rectangular shape that has equivalent hydrologi...

Diffusion and Brownian motion in Lagrangian coordinates.

In this paper we consider the convection-diffusion problem of a passive scalar in Lagrangian coordinates, i.e., in a coordinate system fixed on fluid particles. Both the convection-diffusion partial differential equation and the Langevin equation are expressed in Lagrangian coordinates and are shown to be equivalent for uniform, isotropic diffusion. The Lagrangian diffusivity is proportional to...
