TOWARD GENERALIZATION OF CALCULATIONS OF THE STATIONARY VELOCITY OF DIFFUSION FLAME PROPAGATION OVER THE SURFACE OF A FUEL
A. I. Karpov,a A. A. Galat,a and V. K. Bulgakovb UDC 536.46:536.75 The results of numerical investigations of the laws governing the spreading of a two-dimensional diffusion flame over thermally thin layers of a cellulose material using the algorithm of calculation of stationary velocity of flame propagation, which is based on the principle of minimum entropy production, are presented. The obtained dependences of the velocity of flame propagation on thermophysical parameters (thickness of the fuel, oxygen concentration and pressure of the ambient, velocity of the blowing flow) agree quantitatively with the well-known experimental data. aInstitute of Applied Mechanics, Ural Branch of the Russian Academy of Sciences, 34 Baramzina Str., Izhevsk, 426067, Russia; email: karpov@udman.ru; bPacific Ocean State University, 136 Tikhookeanskaya Str., Khabarovsk, 680035, Russia.
