Abstracts:

Numerical and experimental researches of integrated characteristics of gel and propellant fuels ignition by typical sources of limited power consumption – the single heated to high temperatures metal and nonmetallic particles of the small sizes are executed. The mathematical model of gel fuel gas-phase ignition is developed in two-dimensional statement and considers processes of heat conductivity, fuel and oxidizer evaporation, a diffusive and convective heat and mass transfer in around area, and besides oxidations of combustible gases. The mathematical model of metallized propellant ignition does not consider process of fuel gasification during the induction period, ignition happens in the condensed phase. Experimental researches are conducted at the equipment of modern measuring PIV-system and the heating furnace. By results of researches the analysis of influence of power source heat content on ignition time delay is carried out.
