flame, probability theory, distribution of fractions, integral function, enthalpy, adiabatic temperatureAbstract
To solve the problem of determining the flame temperature in the working space of the thermal units, it is proposed to calculate a change in adiabatic enthalpy methods of the probability theory (TV). It is shown that the normal distribution function of fuel cells allows one to obtain the integral distribution function of enthalpy and adiabatic temperature along the length of the flame. The problem is solved with respect to a homogeneous diffusion gaseous flame at various numbers of diffusion massiveness and homogeneous and the laminar regime of motion of the combustion components. For the purpose of generalization of the solution оn the channels of canonical forms the corresponding dependences are offered. The range of change of mass-exchanged number of Bio and the convergence of the sum of the series for the regularization of the solutions of the equation combustion surface by the method of Burke-Schumann are determined. An explanation is offered for the S-shaped shape of the temperature curve observed when almost all fuels are burned in the installations of various types; its connection with the integrated function of distribution of fuel volumes is also provided.
