MODELING OF GAS DYNAMICS IN A PULSE COMBUSTION CHAMBER TO PREDICT INITIAL DRYING PROCESS PARAMETERS

摘要

A mathematical model of gas-dynamical processes in a pulse combustion chamberrnfor drying of materials is formulated with regard for the second viscosity. Results ofrnnumerical solution of the gas-dynamical problem are reported. In particular, it is shownrnthat the time dependences of the gas pressure and velocity represent sinusoidal plots withrna phase shift. Introduction of the dissipation term with a second viscosity factor is foundrnto stabilize a computational process.
