碩士 === 國立高雄應用科技大學 === 機械與精密工程研究所 === 96 === Mixed convective heat and mass transfer of newtonian fluids in a channel is numerically investigated in this study. The fluid flows into the channel from the left opening and exits from the opposite end. Both the temperature and the velocity of the inflow fluid are kept constant. A heated block moves forward and backward periodically in the center of the channel. The numerical computations were obtained using the cubic spline collocation method in a personal computer. The governing equations,including stream function, vorticity, microrotation and energy, were first put in dimensionless form. The governing parameters appearing in present study are Re,Gr,Sc, .The numerical results of the flow fields are discussed with plots and table of isotherms, streamlines and concentration. The results indicate that the effect of mixed convective heat transfer and mass transfer depends on the moving block signiticantly.
