Modelamiento y simulación de un intercambiador de calor

Abstract

This issue of heat exchanger is focused on mathematical modeling and simulation in different software, starting with a brief introduction of related concepts to the heat exchanger, then the equations that model the dynamic system of our heat exchanger will be analyzed, for satisfaction will be resolved and analyzed. Analyze the first-order differential equation that models the behavior of the heat exchanger shell and tube, simulate the nonlinear equation and observe their behavior with respect to two inputs of step-like response, then we will apply the Laplace transform and using linearized deviation variables achieve for its transfer function and to compare it with the software we use. MATLAB on the one hand is a program that must be licensed to use, also the visual programming environment SIMULINK works on the MATLAB environment also use the SCILAB program is free and open source license and also with his Xcos visual programming environment that is similar to SIMULINK finally simulate a language for modeling object-oriented MODELICA, which like the previous program is free software.
