Analysis of Counter Flow Heat Exchanger Using Copper as A Material
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
The general function of a heat exchanger is to transfer heat from one fluid to another. The basic component of a heat exchanger can be viewed as a tube with one fluid running through it and another fluid flowing by on the outside. The temperature gradient or the differences in temperature facilitate this transfer of heat. Transfer of heat happens by three principle means conduction, convection and radiation. In the use of heat exchangers radiation does take place. However, in comparison to conduction and convection, radiation does not play a major role. The objective of present work involves the study of refinery process and applies phenomena of heat transfer using copper as a material for thermal design of counter flow heat exchanger. The inner pipe in which hot hydrocarbon flows and in outer annulus cold crude oil passes from opposite direction. The heat recovery from hot fluid is used to increase the temperature of cold fluid. Design was carried out based on the outlet temperature requirement of the cold fluid. With the help of computation fluid dynamics the study and unsteady simulation carried out for designed heat exchanger and based on the simulation results thermal analysis carried out.
