Analisa Pengaruh Laju Alir Fluida Terhadap Nilai Efektivitas Untuk Menguji Kinerja Alat Penukar Panas Jenis Shell and Tube (Analysis of Fluid Flow Rate Effect on the Effectivity Value for Performance Test of Shell and Tube Heat Exchanger)

Abstract

Heat exchanger is an equipment to exchange heat between two kinds of fluid or more. As a device to exchange heat from hot fluid to colder fluid, a heat exchanger is supposed to have high effectiveness. Theoretically, the increase of fluid rate would increase the effectiveness. Yet, it makes the contact time among the fluids become shorter. Based on this phenomenon, a research is carried on to find out how the fluid rate affects the effectiveness of a Shell-and-Tube Heat Exchanger. The working fluid used is water. It is found out that the effectiveness would up to a certain value if the fluid rate increases and then it would decrease.
