Parametric Study of Entropy Generation in a Fluid with Internal Heat Generation between Two Rotating Cylinders Subjected to Convective Cooling at the Surface

الملخص EN

Entropy generation analysis of a steady fluid flow with internal heat generation between two rotating cylinders was presented.

The surface of the inner cylinder was kept at constant temperature while the surface of the outer cylinder was exposed to convection cooling.

Analytical expressions for velocity and temperature distributions within the fluid were obtained.

The effects of velocity ratio, Biot number, Brinkman number and other dimensionless parameters on the temperature distribution and local and total entropy generation rates were investigated and the results were presented graphically.
