Temperature-Dependent Viscosity Effects on the Thermohydraulics of Heated Porous-Medium Channel Flows
Краткое описание
Using numerical simulation results, the evolution of the Modified Hazen-Dupuit-Darcy (M-HDD) model, which incorporates temperature-dependent viscosity effects in the prediction of global pressure drop across a heated porous medium channel, is discussed. New flow regimes that owe their existence entirely to variable viscosity effects (thereby explained only by the M-HDD model) are exposited. Temperature-dependent viscosity effects on the departure from Darcy flow to nonlinear (form-drag dominant) flow regime is analyzed in detail. The transition, from linear Darcy flow of a fluid with viscosity decreasing with temperature, is shown to happen at an earlier global velocity than for the constant-viscosity counterpart. Finally, experimental appraisals that support the validity of the M-HDD model are also discussed.
