Plate Heat Exchanger (PHE) is an important part of a condensing or evaporating system. Among many of factors which should concentrate on, the heat transfer and pressure drop is most important part during sizing and rating the performance of PHE. Due to the complex corrugated surface design flow is highly turbulent. This makes design of plate heat exchanger using empirical correlations to deviate from actual. Sometimes flow medium cannot distribute uniformly which affects the performance of plate heat exchanger. The optimization problem is formulated as the minimization of the heat transfer area, subject to constraints on the number of channels, pressure drop, flow velocity and thermal effectiveness, as well as the exchanger thermal and hydraulic model. Nowadays PHE widely use in different industries such as chemical, food and pharmaceutical pr...

Infact buoyancy driven convection in a sealed cavity with differentially heated isothermal walls is a prototype of many industrial applications such as energy efficient buildings, operation and safety of nuclear reactor and convective heat transfer associated with electronic cooling equipment. The internal flow problems are considerably more complex than external ones. In electronic systems normally the heat generating bodies exist within the cavity. The effect of the presence of heat source on the mass flow rate and heat transfer is considered in present case for investigation. In order to verify the methodology of using fluent, the commercial software, the available problem in the literature is verified for parametric study on the location of heat source and its strength is considered for study. In present work, the given source is split into two parts and its effect on the flow rate and heat transfer is studied. An attempt is made for the best location of the heat source in the cavity so that it can be used in the electronic equipment generating heat.
