Heat Exchanger Analysis Laboratory Report
Abstract
The experiment conducted was to analyse the work of a heat exchanger, by studying the effects of heat transfer from a hot stream and a cold stream in the heat exchanger. In the experiment we were introduced to the shell and tube heat exchanger and were told of all its parts and how to use them. The experiment started by evaluating what the heat transfer rate for a hot stream and a cold stream was within the heat exchanger. Using this information the experiment went on to analyse the heat exchanger in more detail. The log mean temperature difference approach and NTU-effectiveness approach were used to calculate heat transfer UA value and the effectiveness of the heat exchanger respectively.
The report begins with the introduction into the experiment and gives a detailed account of the background behind heat exchangers and especially the shell and tube heat exchanger. This is followed by the list of objectives of the experiment, telling exactly what was expected from the laboratory and what information we wanted to gather from the experiment. The theory section explains the logic behind some of the formulas used and results gathered.
The experiment as a whole is discussed with the experiment’s method explaining all the steps taking during the experiment and the different values measured. The experimental results show the values and graphs behind the different properties of the heat exchanger.
My own opinion on the results obtained and my understanding of heat exchangers from the experiment is discussed in the conclusion of the report.
Introduction
The experiment carried out was to investigate the process of heat energy transfer between two fluids at different temperatures, a hot stream and cold stream. A heat exchanger is a device that utilizes this principle of heat transfer. The heat exchanger consists of two flowing fluids separated by a solid wall; this prevents the fluids from mixing with each other. Appliances that use heat
