Methane, ethane, propane, methanol and ethanol are used as fuels. Emphasis is placed on the effects of viscosity, specific heat and thermal conductivity on the Prandtl number. It is disclosed from the present study that (i) the Prandtl number of combustion gas is substantially affected by thermal conductivity of H_2O, (ii) if the equivalence ratio (φ) or temperature is the same, the higher Prandtl number of combustion gas is evaluated for the case of ethanol, and (iii) the maximum value of the Prandtl number is obtained at φ=1 for any fuels used here.}, pages = {5--10}, title = {燃焼ガスの熱物性に関する研究}, volume = {36}, year = {1994} }
