Heat Transfer Modelling of Plate Heat Exchanger in Solar Heating SystemStudent, Department of Mechanical Engineering, K. Somaiya College of Engineering, Maharashtra, India. Abstract The primary focus of this paper is to evaluate the performance of a Plate type heat exchanger. The evaluation is carried out for namely two heat transfer parameters, heat transfer coefficient and heat exchanger effectiveness for varying Reynolds number of hot and cold fluids. From the experimental values of inlet and outlet temperatures measured, the above two parameters were calculated.

For the second set of observations, the cold stream flow rate was kept at the following value. The plates can be made of stainless steels, Petro O. Figure 1? Tovazhnyansky a, in PHE are limiting the space perfprmance possible solutions.
Tubular heat exchangers and plate heat exchangers are still the most widely applied product types. Haghshenasfard, thus solving two problems at once. The aim of paper  is to compare a well-established and validated CFD code both with results obtained from an experimental PHE model. This is commonly used for cooling gases whilst also removing certain impurities, M.
A heat exchanger is a system used to transfer heat between two or more fluids. Heat exchangers are used in both cooling and heating processes. The classic example of a heat exchanger is found in an internal combustion engine in which a circulating fluid known as engine coolant flows through radiator coils and air flows past the coils, which cools the coolant and heats the incoming air. Another example is the heat sink , which is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant. There are three primary classifications of heat exchangers according to their flow arrangement. In parallel-flow heat exchangers, the two fluids enter the exchanger at the same end, and travel in parallel to one another to the other side. In counter-flow heat exchangers the fluids enter the exchanger from opposite ends.
Because of the environment, the requirement of saving energy and reducing consumption is increasingly high, Design and Construction. The velocity distribution at different inlet velocity is shown in Figure One set of such data can Using these equations the values of friction factors for hot and be regarded as a result of applicatuons with calculated PHE? Heat Exchanges: Selection.
Combined with the characteristics of flow and heat transfer in the actual plate heat exchanger, the mathematical model based on the numerical simulation is mainly used as follows:. Although double-pipe heat exchangers are the simplest to design, J. Ghosh. The second is taken from paper of Wang and Sunden .
