Experimental Study of Forced Convection Heat Transfer of a Cam-Shaped Tube and a Cylinder in an External Laminar Flow

Forced convection heat transfer of a cam-tube and a cylinder in external laminar flow and at Reynolds number in the interval 7×〖10〗^4to 1.2×〖10〗^5areexperimentally implemented.Nusselt number distribution and its varying in terms of Reynolds number for prototypes (Cam-tube and cylinder) are treated. The principle result indicates applying the Cam-tube instead of cylinder make it possible increase the heat transfer between 5 to 22 percent. The uncertainty of the gathered data was at minimum 12 percent and at maximum 22 percent. Furthermore,the results show that theHilpert’sequationisauthentic for the treated cam-tube.
