| Abstract | ||||
| An experimental investigation has been presented to study the forced convection heat transfer from a cross yawed circular tube with back splitter plate. The course of the experimental work covers Reynolds number range from 9500 to 54700, the wake splitter length varied from b = 0 to 1.5d° and the yaw angle of tube changes from 0° to 30° with respect to the cross slow orientation. The obtained results are compared with the available data in the literature. The heat transfer from the yawed tube with splitter plate is fitted as a correlation between the Nusselt, Reynolds and Prandtl numbers. This correlation indicates that the Nusselt number is a significant function of Reynolds number, yaw angle and splitter plate length. It is also seen that the effect of the yaw angle on the convective heat transfer from the tube is less than the effect of the splitter plate length, and the yawed tube with back splitter plate of length b=0.75d° and θ=30° has higher results than the other cases. A dimensionless correlation is obtained to calculate the convective heat transfer Nusselt number as a function of yaw angle, splitter plate length, Reynolds number and Prandtl number. | ||||
