Laminar Forced Convection Heat Transfer from Isothermal Bodies with Unit Aspect Ratio

摘要

In this paper a semi - analytical approach is employed to obtain dimensionless heat transfer correlations for forced convection over three geometries sphere, cone and cylinder with unit aspect ratio in laminar axial air flow. The results for sphere were compared with previous results; where the comparison was very good. Validation of results for cone and cylinder were done based on available data on drag coefficients. Finally a general correlation is developed for a rough estimate of forced convection from isothermal bodies of unit aspect ratio.
