A method for measuring the thermal diffusivity of solid materials under combined boundary conditions in combination with the idea of inverse heat transfer problem is proposed. Based on the idea of the finite volume method and the alternating direction implicit method. MATLAB software is used to numerically solve the temperature field of the forward problem. The conjugate gradient meth... https://www.spidertattooz.com/Army-Crest-13Th-Signal-Battalion-Voice-of-Command/
