Balance Molecular Equation

The GUI application allows the user to enter the parameters of the Antoine equation and then plot vapour pressure of any chemical component versus temperature.

The Two Dimensional Schrodinger Equation model simulates the time evolution of a two-dimensional wave packet as it moves towards a slit with an obstacle in it, both with variable widths. By changing three parameters via sliders provided, slit width, obstacle width, and initial position of the...

The EJS Molecular Dynamics model is constructed using the Lennard-Jones potential truncated at a distance of 3 molecular diameters. The motion of the molecules is governed by Newton's laws, approximated using the Verlet algorithm with the indicated time step. For sufficiently small time steps dt,...

This is a very simple app that displays your remaining credit balance on a Pay-as-you-go phone. I wrote it for a family member who wanted a simple one-click way to find out her balance. I found you can display the balance by dialling the number *#1345# so that is exactly what this app does, but...

The project, launched by Chris Crawford, is a remake of his environmental simulation game 'Balance of the Planet'. The complete game mechanics will be rewritten from the original sources and additional resources will be added (images, sounds, music...)

Flow past a wedge is governed by the Falkner-Skan equation. This equation admits only numerical solution, which requires the application of the shooting technique. The program plots the velocity for various wedge angles. The result obtained is in agreement with figure 8-10 in page 352 of Deen's...

In the programs, we perform flash calculations of a mixture of hydrocarbons (ethane, propane, n-butane and n-pentane) using the Rachford-Rice equation. The phi-phi method, based on the SRK equation of state, is used to compute the equilibrium constants. We also find the True Vapor Pressure. All...

We solve a binary distillation problem using the solution of a Riccati equation. We find that four plates are needed to achieve the desired product purity. We also compute the number of stages with the classical approach by stepping off stages using the equilibrium curve and the operating line....

In this paper i try to associate a linear dynamical system dX/dt=AX to the PDE wave equation.So i discretize the space to step h,and set the limited develpment.it is well application also for spherical wave.J.C Willems gives good standing from ODE to PDE,and From PDe to ODE.
