A design of a tube and shell heat exchanger for non-newtonianos fluides based on kern and tinker methods

Dimensionamiento de un intercambiador de calor de tubo y coraza para fluidos no newtonianos por los métodos de Kern y Tinker

Shell and tube heat exchangers are used in food, chemical and pharmaceutical industries. A heat exchanger was projected for heating orange juice with 27°Brix. The methods Kern and Tinker were applied because they are the most known and available in the literature. The results show the discrepancies between the two methods up to 300% of divergences in the hydraulic project and 70% in the convection coefficient of heat transfer
