This work deals with a study on the laminar convective heat flow of a homemade air condition ing unit through a computational fluid dynamics simulation. With adoption of chilled water as the working fluid within a tube section of the evaporative compartment of the homemade air conditioner whose radius is 5mm and Height 20mm .The numerical analysis was carried out using COMSOL MULTIPHYSICS.Simulation was carried out, using (276 (3属C) as the inlet temperature and 293 (20属C) as the outlet temperature with a flow rate of 0.15 m3 s. The result showed the velocity profile of the working fluid and the temperature distribution before, during and after heat exchange, helping to achieve a Visual understanding of the Laminar convective fluid and heat flow phenomena within the cooling coil.]]>

Different analytical and numerical methods are commonly used to solve transient heat conduction problems. In this problem, the use of Alternating Direct Implicit scheme (ADI) was adopted to solve temperature variation within an infinitesimal long bar of a square cross-section. The bottom right quadrant of the square cross-section of the bar was selected. The surface of the bar was maintained at constant temperature and temperature variation within the bar was evaluated within a time frame. The Laplace equation governing the 2-dimesional heat conduction was solved by iterative schemes as a result of the time variation. The modelled problem using COMSOL-MULTIPHYSICS software validated the result of the ADI analysis. On comparing the Modelled results from COMSOL MULTIPHYSICS and the results from ADI iterative scheme graphically, there was an high level of agreement between both results.]]>
