Effects of mass transfer and flow past a moving vertical cylinder with constant heat flux

The authors present a numerical investigation of laminar natural convection flow past a moving semi-infinite vertical cylinder subjected to constant h eat flux. The transformed governing equations are obtained and solved using an implicit finite difference scheme of Crank-Nicolson type. Numerical res ults for the transient velocity, the temperature and the concentration prof iles are shown graphically. It is observed that there is a rise in temperat ure due to the presence of mass diffusion. The local as well as average ski n friction, and the rate of heat and mass transfers are shown graphically.
