Parametric variation of the maximum surface temperature during laser heating with convective boundary conditions

Modelling of laser pulse heating of metallic substrates reduces the experimental cost and optimizes the laser heating parameters. In the present study, exponentially time-varying laser pulse heating with convective boundary conditions at the surface is considered. The closed-form solution for temperature distribution at the surface is presented. The effects of the heat transfer coefficient (h^*) and pulse parameter (β^*) on the time corresponding to the maximum surface temperature (t_Tmax^*) are investigated. It is found that the influence of the heat transfer coefficient on t_Tmax^* is significant for h^*≥0.02. Moreover, reducing the pulse parameter lowers t_Tmax^*.
