Analysis of Combustion Processes by Stochastic Reaction Diffusion Systems and Simulation Studies

抄録

In this paper, the difference between combustion processes of gaseous fuel in gravitational and microgravitational fields are studied by simulations. And the influence of disturbances such as impurities in fuel and thermal fluctuations on combustion processes are examined by simulations. In the gravitational field, gaseous fuel is supplied by convection, on the other hand, it is supplied by diffusion in microgravitational field. It follows from this fact that the difference in combustion processes arises in both fields. In simulations, we show how the combustion processes change depending on the time constant of reaction and the ratio of diffusivity of gaseous fuel.
