Numerical study of flow and heat transfer in differentially heated enclosures

Abstract

Two-dimensional laminar natural convection is studied numerically for differentially heated air-filled rectangular enclosures with adiabatic side walls and aspect ratios of 1, 2, 4, and 8. The inclination angle of the enclosure was varied from 0° to 180°, and the effect of inclination on flow field and heat transfer was investigated over the range 103
