Abstract

Paper presented to the 10th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Florida, 14-16 July 2014.
The present paper propound an analytical inverse method to calculate the heat transfer coefficient of cutting fluids in machining processes. 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.
