Abstract: | This article investigates the natural convection flow of viscous incompressible fluid in a channel formed by two infinite
vertical parallel plates. Fully developed laminar flow is considered in a vertical channel with steady-periodic temperature
regime on the boundaries. The effect of internal heating by viscous dissipation is taken into consideration. Separating the
velocity and temperature fields into steady and periodic parts, the resulting second order ordinary differential equations
are solved to obtain the expressions for velocity, and temperature. The amplitudes and phases of temperature and velocity
are also obtained as well as the rate of heat transfer and the skin friction on the plates. In presence of viscous dissipation,
fluids of relatively small Prandtl number has higher temperature than the channel plates and as such, heat is being transferred
from the fluid to the plate. |
