|Abstract:||A numerical model was developed to study the effects of rotation on the fluid motion and heat-transfer processes in the annual space between eccentric cylinders when the inner cylinder is heated and rotating. Experimental verification is based on the calorimetric technique. Comparison is made between the numerical and experimental results for a moderate radius ratio of 2. 6 with eccentricities of 0, 1/3, and 2/3. The overall equivalent thermal conductivity (K//e//q) is obtained for Rayleigh numbers Ra up to 10**6 with rotational Reynolds number Re variations of 0-1120. The Prandtl number Pr of the fluid chosen is 0. 7 for air. Investigation shows that, for Re up to the order of 10**2, the numerical model shows promising results when Ra is increased.|
