“…The position of the maximum temperatures region does not correspond to the region of maximum reaction rates and the position of the combustion flame front, since under reduced gravity conditions there are no convective flows that play a major role. Flame front instabilities occur during the transient conditions, which eventually decay and, as shown earlier [4], under the advanced microgravity conditions, the flame is subjected only to high-frequency oscillations. At the same time, the oscillations are so strong that the plume parts are separated from the main plume and moved downstream the flow.…”

The work is devoted to the analysis of the methane-air conical flame behaviour under conditions of an alternating gravitational field. Numerical simulation based on the software package FlowVision, has shown the possibility of modeling the flame front instabilities during the transition from the normal gravitational conditions to zero gravity. The appearance of the flame front oscillations is demonstrated under the such conditions. Further studies will provide a complete picture of the behavior of the flame in an alternating gravitational field.
