Abstract
The shell and tube heat exchanger is an equipment largely used at chemical industries. The most known methods used for its design are the methods of Kern, Bell-Delaware and Tinker, for what a lot of equations are necessary. In this way, the calculation without using any computer aid takes a lot of time. This paper present a didactical software developed for the design of shell and tube heat exchanger and heat exchangers networks, this last one using Pinch analysis. The software called heat exchanger simulator (HES), was developed to be used in undergraduate classes of Chemical Engineering. Since the use of a software can decrease the necessary time for evaluations, a fairly more time can be saved, which can be used in the analysis of the results, study of parametric sensitivity, research of backing subjects, amongst other essential tasks in the modern context of engineering. The use of the software facilitates the development of individual or group projects, in which the situation can develop its creativity through the scanning of a real problem. The benefits of such practice are several, being the starting point for the process of stand alone and continued education, unique capable to allow the future professional to remain itself brought up to date with the increasing development of new technologies.
