Research work is about solving Heat equation, exactly, One phaseStefan problem, which, solved with modern method, called Integral Error Function by Hartree. Stefan problem consider heat transferring in electrical contact from one phase to the second. Simple example to the Stefan problem are the melting of ice and the freezing of water. To solve the Stefan problem, which is known problem in numerous industrial and technological applications, such as the manufacture of steel, ablation of heat shields, contact melting in thermal storage systems, ice accretion on aircraft, evaporation of water, used the program «Matlab» by approximation method. Physical meaning of this research is finding melting point by giving heat flow.enIntegral error functionStefan problemHeat equationstemperatureapproximation.СДУ хабаршысы - 2018№4Article
