INVESTIGATION OF HEAT TRANSFER ON TWO ADJACENT NARROW PLATES WITH NATURAL CONVECTION

Abstract

Natural convection flow in a vertical channel containing inside objects exists in a number of advance technological applications, including heat transfer from electronic circuits, refrigerators, heat exchangers, power station, fueling components, chillers, and residential ventilation, etc. In this thesis the model is created in CREO, and then imported into ANSYS to simulate air flow through vertical thin plates. The focus of the thesis will be on thermal and CFD modeling of vertical thin plates with variable Reynolds numbers (2×106& 4×106) and at angles (0°,30°&60°) respectively. Thermal analysis was performed on vertical thin narrow plates made up of steel, aluminium, and copper at various heat transfer coefficient rates.Modeling and analysis of the narrow vertical plate is demonstrated utilising the data books details and design formulary.CFD analysis results tabulated at different Reynolds number, pressure, velocity, heat transfer coefficient, mass flow rate and heat transfer and also which is drawn into graphical representation.3D modelling was done in the parametric application Pro-Engineer, and analysis is performed in ANSYS.
