Professor Jim Wilkes provides representative values of the volumetric flow rate versus the applied pressure gradient for horizontal flow in a pipe [1]. The pipe radius is equal to 0.01 m. We use these representative values, in conjunction with the analytical expression of the volumetric flow... Platforms: Matlab

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... Platforms: Matlab

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... Platforms: Matlab

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.... Platforms: Matlab

The program 'Efinder' numerically solves the Schroedinger equation using MATLAB's 'ode45' within a range of energy values. By taking advantage of the dramatic endpoint behavior of the resulting wave solutions, 'Efinder' determines the eigen energies to any accuracy needed.This program has been... Platforms: Matlab

Two mass variable equations with "Aerospace 3Dof Simple Variable Mass Blockset" are compared in a 1Dof frictionless environment. Initial conditions are given in Model Callbacks.Results showed that "Aerospace 3Dof Simple Variable Mass Blockset" uses the incorrect equation. Platforms: Matlab

this is the first generation of the 'fig2real' programme. i will modify it and upload it again.this programme used to get the plynomial equation of curve drawn on picture.....thanks mathwork Platforms: Matlab

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. Platforms: Matlab

From undergraduate chemistry, we know how to test whether a reaction is 0th, 1st, or 2nd order by plotting different transformations of the data, and inspecting which plot fits the best.This program does the same thing. It transforms the data using different values of the order, attempting to... Platforms: Matlab

Boundary Control via Modified Smith Predictors for Beam Equation with Delayed Boundary MeasurementSmith predictor and its variants are applied to the boundary control of Euler-Bernoulli beam equation with delayed boundary measurement. The well-known instability problem due to a small time delay... Platforms: Matlab

Solves nonlinear diffusion equation which can be linearised as shown for the general nonlinear diffusion equation in Richtmyer & Morton [1]. The approach is to linearise the pde and apply a Crank-Nicolson implicit finite difference scheme to solve the equation numerically.Matlab run... Platforms: Matlab
