Abstract
Transient free convection flow of water at 4°C past an isothermal semi-infinite vertical plate, when its density is maximum, is analysed by employing an explicit finite-difference technique. The transient velocity and temperature, the average skin-friction and the average Nusselt number are shown graphically for Prandtl number Pr=11.4 (4°C) and 7.0 (20°C). It has ben observed that when the density of water is maximum, it takes more time to reach its steady state. Also the average skin-friction decreases considerably when the water is at 4°C, as compared to that at 20°C. The average Nusselt number increases at small values of time and decreases at large values of time when the water is at 4°C.
