Description

2.0 INTRODUCTION A heat exchanger is a device that allows heat from a fluid a liquid or a gas to pass to a second fluid which is another liquid or gas without the two fluids having to mix together or come into direct contact. In this model, two separated fluids at different temperatures flow through the heat exchanger: one through the tubes tube side and the other through the shell around the tubes shell side. The two fluids can flow in the same direction (known as parallel flow), in opposite directions which are counter flow or counter-current, or at right angles cross flow. (Chris,2016) Parallel flow or co-current flow is the flow where the hot and the cold fluid is flow in the same direction. The most effective flow in the heat exchanger is a countercurrent flow where the fluid paths flow in opposite directions, with exiting and the other enters. This results in faster heat exchange. For this experiment, counter-current heat exchanger is used. In counter flow heat exchangers, the two fluids flow against each other, maintaining a maximum temperature difference between the hot and cold streams which allows for maximum heat transfer.
