Correlations for Convective Laminar Heat Transfer of Carreau Fluid in Straight Tube Flow

Correlations for the Nusselt number fully-developed laminar flow of Carreau fluids through circular pipe subject to a uniform heat flux have been sought. Based on mathematical expression, could be obtained by numerical integration. To evaluate many conditions, an efficient integration method has proposed. Using different material constants and improved correlation The proposed reduce maximum error from 3% 0.9%.
