INFLUENCE OF DISSIPATION ON HEAT TRANSFER DURING FLOW OF A NON-NEWTONIAN FLUID IN A POROUS CHANNEL

A study is made of fl ow and heat transfer during the motion of a non-Newtonian (power-law) fl uid in a plane channel fi lled with porous material. The Brinkman equation is used as the equation of state, and a one-temperature model, in representing the energy equation. Account us taken of dissipative heat releases. The problem is solved for temperature boundary conditions of the fi rst kind. The authors show the infl uence of dissipation on the development of the temperature profi le, and also on the distributions of the local Nusselt number and the mass-mean temperature along the channel.
