...J. M. Floryan; N. N. Haq; S. Panday An analysis of natural convection in horizontal slots has been carried out. It is demonstrated that a proper combination of heating and groove patterns can create a net horizontal fluid movement, which we refer to as the horizontal chimney effect. Groove shapes...

... rises. Sabbah et al. [ 11 ] studied numerically the effect of the presence of a micro-encapsulated phase change material on natural convection in a rectangular cavity. The numerical results showed a significant increase in the heat transfer coefficient (up to 80%) at the considered operating conditions...
