Non-stationary model for calculation of the parameters engine combustion chamber workflow

The article presents a model of non-stationary work flow gas-dynamic parameters of the working process in the a rocket engine combustion chamber for solid fuels with a relatively large channel length of variable solid fuel charge cross-section (pic.1). The model is in the two-dimensional formulation. The problem is solved by the grid method – the channel is divided along the z axis into equal cells, several capabilities subscript j.

The mathematical model provide:

– Quantitatively analyze the shock-wave processes in solid propellant with a relatively large channel length of variable cross-section of the charge solid fuel [pic.1],

– Calculate temperature distribution and flow rate of combustion products of the igniter composition and solid fuel over the channel length.

– Calculate the speed and depth of the of solid fuel surface warming-up and combustion wave propagation in a of the charge solid fuel channel after its ignition in the most heat zones of the surface.

Keywords
