Diseño y simulación de un intercambiador de calor de tubo y coraza con una capacidad de 31 m3/h para el proceso de enfriamiento de agua hasta 16 °C en la Planta Sigmaplast

Abstract

The purpose of this study is to show through a simulation using the Flow Simulation plug-in of the Solidworks software the water-cooling process using a shell and tube heat exchanger which performs the heat exchange process using convection, the fluids working temperatures are water at 22 ° C and 16 ° C. The methodology was developed based on a quantitative approach since the process presents certain steps regarding the operation of the shell and tube heat exchanger. The geometry used for the design of the equipment helps to have an evaluation of the thermal behavior of the fluids that interact in the heat exchange process. The use of baffles within the design helps to reduce the surface area of heat transfer and through simulation it is possible to observe this advantage. The normal heat transfer rate calculated was 236.18 kW, while the results delivered by the simulator show that the adequate length for the internal tubes is 1 m and that the efficiency of the heat exchanger is 54.51 % and, therefore, Therefore, the average temperature obtained after performing the 3 simulations is 15.55 °C, giving an error of 3.21 %.
