Heat transfer in an absorbing and emitting nongray Boussinesq fluid within the annular gap of two infinitely long isothermal horizontal concentric cylinders is studied analytically. The Milne-Eddington approximation is employed in expressing the two-dimensional radiative transfer to include radial and ...
This article is concerned with the examination of flow dynamics and heat transfer characteristics in a 1:4 double lid driven cavity in presence of isoperimetric heated blocks of various shapes. The focus is to identify the optimal shape that enhances the heat transfer in a tall cavity. The para...
Natural convection heat transfer from horizontal concentric cylinders is studied experimentally and numerically. Concentric cylinders were formed with two test cylinders made of copper, and the annulus was filled with water. Concentric cylinder system was located in the ambient air and the inner horizonta...

HEAT TRANSFER BEHAVIOR OF NON-NEWTONIAN CARREAU FLUID BETWEEN ROTATING CONCENTRIC VERTICAL CYLINDERSLaminar flow and heat transfer mechanism of a non-Newtonian fluid in the annular space between two coaxial rotating cylinders is analyzed. The problem is considered when the inner cylinder rotates about...
