A numerical study is performed on unsteady natural convection heat transfer and fluid flow in a square cavity in free fall. Consideration is given to the influence of gravity on the thermal and velocity fields in a square cell with two opposing vertical side walls held at constant but different temperature with the remaining horizontal walls insulated. The governing boundary-layer equations are discretized by means of a finite-difference technique and numerically solved It is disclosed from the study that: (i) in free fall, the fluid temperature gradient is substantially decreased near the hot and cold vertical walls, (ii) but as time progresses, the dominant heat transfer mechanism switches from convection into conduction, and (iii) if the reduced gravity level in free fall is under 10-4g, the effect of gravity on the thermal transport phenomena becomes minor.
