The programs compute the bifurcation diagram for the cubic map and a realistic population dynamics model. The value of parameter r, when the cycle of period three appears, is indicated. As expected, for higher values of r, we observe chaotic behaviour. Both models are given in the problems? section (problems 2.34 and 2.35; page 207) in Varma and Morbidelli, Mathematical Methods in Chemical Engineering, Oxford University Press, 1997. This work...
The programs compute the vapor-liquid diagram of an ethane-benzene mixture at 25dlT-C and 175dlT-C. This binary mixture exhibits a peculiar behavior because the volatilities of ethane and benzene are very different. We use the SRK equation of...
Computation of the residue curve map for the MTBE chemistry is presented in the program. The equilibrium, taking place in the liquid phase, transforms methanol and isobutene into MTBE with n-butane being an inert component. Thermodynamic data can...
The program computes the liquid-liquid equilibrium diagrams for a type II ternary systems based on the NRTL model. The ternary mixture: hexane-heptane-methanol is an example of type II systems. The equilibrium diagram is computed at a temperature...
The program computes the velocity and temperature profiles for free convection past an isothermal vertical plate. Results are obtained after solving two coupled nonlinear differential equations. The shooting method is used to obtain the boundary...
The velocity and shear stress versus radial position are determined for laminar flow of a power law fluid in a pipe. The shooting method is used to verify the no-slip boundary condition at the piped-deOaos wall. Once the velocity at the center is...
Chlorite-iodide-malonic acid (CIMA) reaction gives rise to temporal oscillations. Governing equations and reaction scheme can be found in: (1) I. R. Epstein and J. A. Pojman, An Introduction to Nonlinear Chemical Dynamics, Oscillations, Waves,...
Solves the Lotka Volterra and Oregonator problems using GUI to present the results. The results show a limit cycle typical of nonlinear dynamic problems. This work was performed as a small three month project by junior students at INSAT, Tunis,...
The GUI application plots VLE data of ethanol-water mixture at various pressures. Both Txy and xy diagrams can be plotted at the pressure value specified by the user. The Wilson model allows the program to take into account the deviation from...
Numerical solutions for the conversion of an isothermal axially dispersed plug flow reactor accomplishing first and second order reactions are obtained. The Danckwerts boundary conditions for the so-called "closed" configuration are... |
