Effect of heating coil in commercial shop display cabinet

P Navaneethakrishnan, P S S Srinivasan, S Dhandapani


CFD analysis of flow and temperature distribution in display cabinets used in bakery shops, to keep the foodstuff warm, is attempted using finite volume technique. The display cabinet is modelled as a two-dimensional steadystate natural convection heat-transfer problem. The temperature distribution is affected by a number of parameters of which coil location and coil diameter are important. The effect of coil location arrangement and different coil
diameters at 1000 W input power is investigated using numerical and experimental methods. The measurements are made over a period of 150 min. About 7-13 degrees C variation is observed in the foodstuff placed at various locations. Numerical and experimental results agree well both in magnitude and trend.
