A Modified Hazen - Dupuit-Darcy (M - HDD) model, incorporating nonlinear temperature - dependent viscosity effects, has been proposed recently for predicting the global pressure - drop of nonisothermal flows across a heated (or cooled) porous medium channel. Numerical simulations, mimicking the flow of a liquid with nonlinear temperature - dependent viscosity, are presented now for establishing the influence of inlet temperature on the pressure - drop and on the predictive capabilities of the M - HDD model. As a result, new generalized correlations for predicting the coefficients of the M - HDD model are derived. The results not only demonstrate the importance of fluid inlet temperature on predicting the global pressure - drop but they also extend the applicability of the M - HDD model.
