Thermodynamic Analysis Of Convective Heat Transfer In An Annular Packed Bed, Yasar Demirel, R Kahraman Dec 1999

Thermodynamic Analysis Of Convective Heat Transfer In An Annular Packed Bed, Yasar Demirel, R Kahraman

YASAR DEMIREL

A combination of the first and second law of thermodynamics has been utilized in analyzing the convective heat transfer in an annular packed bed. The bed was heated asymmetrically by constant heat fluxes. Introduction of the packing enhances wall to fluid heat transfer considerably, hence reduces the entropy generation due to heat transfer across a finite temperature difference.

YASAR DEMIREL

Heat transfer behavior of fluid flow through packed tube and channel has an important impact on the de- sign and operation of catalytic reactors.


Thermodynamic Analysis Of Thermomechanical Coupling Incouette Flow, Yasar Demirel Dec 1999

Couette ¯ow provides the simplest model for the analysis of heat transfer for ¯ow between parallel plates and between two coaxial cylinders. Design of such devices with the consideration of the thermo- mechanical coupling of viscous heat generation and Couette ¯ow is important since they are used in lubri- cation, polymer and food processing, and viscometry.
