a new hybrid modal-moment method is proposed to calculate fields penetrated through small apertures on rectangular metallic enclosures. first, the method of moments is used to numerically solve the governing electric field integral equation for the equivalent two-dimensional surface-current distributions on the surface of metallic enclosure including any number of rectangular apertures of arbit...

In the present study, the conjugate turbulent free convection with the thermal surface radiation in a rectangular enclosure bounded by walls with different thermophysical characteristics in the presence of a local heater is numerically studied. The effects of surface emissivity and wall materials on the air flow and the heat transfer characteristics are the main focus of the present investigati...

Widespread commercialization of PCM-based latent heat storage systems is limited by the low melting and solidification rates during phase transition process. In this study, fins are used to enhance change A parametric study conducted understand effect on thermal performance vertically- horizontally-oriented rectangular tanks. Throughout simulations, fin volume, thereby mass PCM in tank, were ke...

In this study, the turbulent buoyancy driven fluid flow and heat transfer in a differentially heated rectangular enclosure filled with water is quantified numerically. The two dimensional governing differential equations are discretized using finite volume method. SIMPLE algorithm employed to obtain stabilized solution for high Rayleigh numbers by computational code written FORTRAN language. A ...

Encapsulation of Phase Change Materials (PCM) for energy storage, thermal comfort and many other applications is receiving much attention due to the fact that material, physical characteristics geometry container can affect drastically performance PCM. change materials have usually low conductivity which impairs their charging discharging characteristics. Different geometries were investigated ...
