Análise da influência de parâmetros termo-hidraulicos em um trocador de calor do tipo casco e tubo utilizando método bell-delaware

Abstract

Most machines that are found today heat during operation. Therefore is necessery to take out heat so the machine can work properly. The cooling occur naturally through air action, or is necessary a coolant with bigger calorific value. In both cases can count with heat exchanger. This work aimed to analyze and better understand the operation and design of a Shell and Tube heat exchanger using the Bell Delaware methodology in order to avoid great number of project changes to meet the ideal one. In order to do so, parameters of the heat exchanger were changed and different configurations were recorded for the equipment and the variations in the equipment exchange capacity using the Bell Delaware calculation methodology of changing heat and compared. A program created in Visual Basic for Application that allowed to change the settings was used as a tool. As results were identified the importance that different parameters represent in the heat exchanger shell and tube project.
