Under the condition featuring a pressure of 0.5 MPa in the combustion chamber,a combustion temperature of 900 ℃,excess air ratio of 1.2 to 1.3 and fluidized speed of 1.1 to 1.2 m/s,the combustion efficiency of the semi-coke can exceed 99% with the carbon content of fly ash being below 2%.
The operation of rocket motors is often accompanied by the development of powerful secondary vortices in the combustion chamber [1-3], The superposition of the secondary vortices on the main flow leads to the formation of a cellular flow structure.
The characteristics of the gas dynamic wave process taking place in a ramjet duct when the combustion chamber is started up or the fuel supply regime is switched have been investigated.
One-dimensional mathematical model of the combustion chamber of a hydrogen/air hypersonic ramjet
A mathematical model of the supersonic combustion chamber of a hydrogen/air hypersonic ramjet is proposed.
Other physical and chemical processes which take place in the combustion chamber, such as excitation of internal molecular degrees of freedom, hydrogen and oxygen dissociation, OH and NO formation, etc., are assumed to be equilibrium.
Weyl chamber flow on irreducible quotients of PSL(2, ?) × PSL(2, ?)
A seaweed-chamber experiment was performed, indicating that gaseous I2 is one of the important precursors that lead to new particle formation in the presence of solar light in the ambient air at the coastal tidal area.
The main process parameters studied in this work were the voltage, the flow rate of the spinning fluid, the distance between the spinneret and the nanofiber collector and the temperature in the spinning chamber.
It ingeniously utilizes the inner space of its chamber by developing its chamber bottom into unsymmetrical ridges along the direction of the inlet and outlet of the pump.
Two Y-shape pipes are fixed outside the chamber serving as an inlet and outlet, with the chamber and a piezoelectric vibrator being the actor.
