| Abstract: | Chemical reactions in turbulent flow are directly affected by gas temperature fluctuations.A way of calculating the gas temperature mean square value by using the governing enthalpy mean square value equation of gases is being presented.Temperature fluctuations of combustion with turbulent swirling diffusion,in a cyclone combustor,is being simulated by this method and the results are compared with experimentally obtained data. |

| Keywords: | engineering thermophysics characteristics of gas temperature fluctuation numerical simulation combustion with turbulent swirling diffusion |
