HEAT CONDUCTION AND HEAT EXCHANGE IN TECHNOLOGICAL PROCESSES MATHEMATICAL MODELING OF THE PROCESSOF WARMING UP OF A CYLINDRICAL SURFACEBY A MOVING INTENSE HEAT SOURCE
O. Yu. Chigireva UDC 536.02 A mathematical model of the process of warming up of a metal cylindrical surface by a moving point heat source has been proposed; the model allows for the presence of a thin absorbing coating on the metal surface and for the thermal resistance of the contact surface. An algorithm of calculation of a nonstationary temperature field has been constructed.; this algorithm makes it possible to find the values of the problem's parameters ensuring local surface heating. An example of numerical calculation has been given. N.E. Bauman Moscow State Technical University, 2ya Baumanskaya Str., Moscow, 105005, Russia.
