Engineering Physics Annotation << Back INFLUENCE OF THE METHOD FOR DETERMINING THE DYNAMIC VISCOSITY OF GAS FUEL COMBUSTION PRODUCTS ON THE ACCURACY OF THE CALCULATION A.V. NUZHDIN, N.YU. KURNAKOVA The article found that the dynamic viscosity calculated by the additivity rule using the volume fractions of the components of the combustion products is less than that determined by the Wilkie method for any excess air coefficients and temperature of the combustion products. And the coefficient of dynamic viscosity calculated according to the additivity rule using the mass fractions of the components of the combustion products is greater than that determined by the Wilkie method for the selected range of changes in the coefficients of excess air and the temperature of the combustion products. Keywords: combustion products; gaseous fuel; dynamic viscosity coefficient; Wilkie method; error. DOI: 10.25791/infizik.6.2022.1272 Pp. 33-38.
