Effect of streamline curvature on turbulent convective heat transfer
Abstract
A lowReynolds number turbulence model has been applied successfully for the fluid flow and heat transfer over convexly curved surfaces. The two test cases chosen are: (1) delta/R=0.01 and (2) delta/R=0.1, where delta is the boundarylayer thickness at the beginning of curvature and R is the radius of curvature. Case (2) also has a new feature of flat surface following the curved one. The model predicted the velocity and temperature profiles as well as friction factor and Stanton number in reasonably good agreement with the experimental data. The agreement with case (1) in particular is excellent.
