Abstract
A study is made of the influence of the mass transfer of water on the temperature field occurring in cartilaginous tissue under the action of laser pulses. Two different mechanism of mass transfer of water in cartilaginous tissue (molecular‐diffusion mechanism and laminar flow) have been considered in solving heat‐ and mass‐transfer equations. The calculations have shown that the maximum temperature is attained inside the sample because of the evaporation of water from the biological‐tissue surface. The influence of different parameters of laser radiation and mass transfer of water on the surface temperature, on the maximum value of the temperature, on the position of the temperature maximum, and on the characteristic time at which the diffusion‐limited relaxation of stresses in the cartilaginous tissue occurs has been analyzed.
