Abstract EN
Experiments were carried out to study the local and average heat transfer by mixed conversation to a simultaneously developing air flow in horizontal, inclined, and vertical concentric cylindrical annulus.
The experimental setup consists of an annulus has a radius ratio of 0.555 and inner cylinder with a heated length 1.2m subjected to the constant heat flux while the outer cylinder is subjected to the ambient temperature.
The investigation covers Reynolds number range from 154 to 845 , heat flux varied from 96 W/m^2 to 845 W/m^2 , and annulus angles of inclinations α=0◦ (horizontal ) , 40◦ , 70◦ , and 90◦ ( vertical) .
Results demonstrate the temperature variation along the inner cylinder surface and the local Nusselt number Nuz variation with the dimensionless axial distance , for all angles of inclinations which shows an increase in the Nuz values as the heat flux increases and as the angle of the inclination moves from the vertical to the horizontal position .
