Nonstationary temperature fields in an isotropic half-space under mixed boundary conditions characteristic of technologies of laser therapy in medicine

Abstract

For the first time, the solution of the heat-conduction equation with mixed boundalw, conditions (BCs) is obtained as applied to the model of an isotropic nontransparent half-space, whose surface z = 0 is heated through the circular region of radius r = R with a heat-flux densi~, characteristic of a laser heat source, while outside of the circle of r > R and z = 0 there occurs intense cooling at the value of the heat-transfer coefficient o~ = oo.
