AB - An experimental method was proposed to assess the natural and forced  convective heat transfer coefficients on highly conductive bodies.  Experiments were performed at air velocities of 0m/s, 4.0m/s, and 5.4m/s, and  comparisons were made between the current results and available literature.  These experiments were extended to arbitrary-shape bodies. External flow  conditions were maintained throughout. In the proposed method, in  determination of the surface convective heat transfer coefficients, flow  condition is immaterial, i.e., either laminar or turbulent. With the present  method, it was aimed to acquire the local heat transfer coefficients on any  arbitrary conductive shape. This method was intended to be implemented by the  heat transfer engineer to identify the local heat transfer rates with local  hot spots. Finally, after analyzing the proposed experimental results,  appropriate decisions can be made to control the amount of the convective  heat transfer off the surface. Limited mass transport was quantified on the  cooled plate.
