This method starts by establishing an estimation of the heat sources in the transient heat conduction dis- tribution in a rectangular domain with convective bounders in free convection. The non homogeneous partial differential equation (PDE) is solved by In- tegral Transform method. The test function for the heat generation term is obtained by model- ing of chip geometry and thermomechanical cut- ting. Then the solution of PDE with heat gener- ation term optimized is used to present an inverse problem to calculate the convective heat transfer coefficient.7 pagesPDF© 2014 University of Pretoria.
