Description
Summary:This paper describes the development of analytical/computational model to evaluate the radial heat flow characteristics in a novel He-SrBr2 laser, which is applied in the surface treatment of biological materials. The model is based on a steady-state heat conduction equation subject to mixed boundary conditions for the radial temperature distribution of the gas in the cross-section of the laser tube. It is assumed a non-uniform distribution of the volume power density. An explicit formula for solving this model is derived. In particular, an expression for calculating the average temperature in the active volume is also established. The obtained results are compared with known simple models.
