Study on Structured Surfaces and Ways to Increase the Efficiently of Heat Exchanger

Heat exchanger is a device which is utilized to exchange heat between two fluids which might be in direct contact or may flow independently in two tubes or channels. We discover various uses of heat exchangers in day today life. In warm power plant heat exchangers are utilized in boilers, condensers, air coolers and chilling towers and so on. Heat exchangers are likewise utilized in substantial scale in synthetic and process industries for exchanging the heat between two fluids which are at a solitary or two states. Enhanced heat exchange efficiency prompts decline in energy utilization which at that point results in lower equipment operational cost, reduced emissions, and therefore additionally bring down ecological effect. Since heat exchange rate depends likewise on flow field attributes, fluid distribution, and fouling which would all be able to be incredibly affected by the real states of flow framework segments, a few improved models for quick and sufficiently precise expectation of fluid distribution and in addition applications for shape streamlining dependent on these models were produced. The primary aim of this thesis is to define the concept of structured surface of the heat exchangers and also to find ways through which we can increase the efficiency of heat exchanger.
