No presente trabalho é apresentada a metodologia de construção e a teoria utilizada para desenvolver um protótipo de um trocador de calor do tipo casco e tubos em conjunto com uma simulação computacional de uma rede de trocadores de calor. O trocador em questão proporciona uma troca de calor através de escoamento em contracorrente, com a entrada do fluído quente na região interna dos tubos de menor diâmetro e escoamento do fluído frio entre os tubos de cobre e a carcaça. São realizadas medidas de temperatura nas regiões de entrada e de saída que proporcionam uma estimativa da eficiência alcançada com o protótipo.
The device used to perform the heat exchange process between two fluids at different temperatures is known as a heat exchanger in which there is the inlet and outlet of the cold fluid and the hot fluid. The heat exchanger most often used in industrial processes is the hull type and pipes. Such equipment is widely used in heating, cooling, evaporation and condensation of fluids. Exchangers of this type have many applications in the power generation, chemical, pharmaceutical and oil and gas industries. This paper presents the construction methodology and the theory used to develop a prototype of a hull and tube type heat exchanger in conjunction with a computational simulation of a network of heat exchangers. The heat exchanger in question provides a countercurrent flow of heat through the flow of hot fluid into the inner region of the smaller diameter tubes and the flow of cold fluid between the copper tubes and the casing. Temperature measurements are performed in the input and output regions that provide an estimate of the efficiency achieved with the prototype.
