Numerical solutions were obtained for R_eR_Ω numbers from 10 to 10^5 (for R_e numbers form 1 to 4200). At low to moderate R_eR_Ω numbers, a double^vortex secondary flow appears under the influence of the Coriolis force. For higher R_eR_Ω numbers it is found that an additional counter-rotating pair of vortices appeared and disappeared for the range of R_Ω numbers from 10 to 100. Correlation equations for friction factors and Nusselt numbers are obtained from numerical results. The numerical results in regard to the friction factor and Nusselt number are in good agreement with experimental and analytical results by other reseachers for circular pipe.
