摘要：

Laminar fully developed flow and heat transfer for Robertson-Stiff fluids in rectangular ducts with temperature dependent viscosity is studied numerically. The viscosity is taken to vary exponentially with temperature. The effect of the temperature dependent viscosity on the behavior of the flow and the heat transfer is investigated. The coupled momentum and energy equations are solved iteratively using finite difference method to obtain the velocity, fanning friction factor and temperature distributions. The average Nusslet numbers are obtained for H-1 thermal boundary condition. Computations are obtained for different values of yield stress, flow index, aspect ratio and viscosity parameters.
