Abstract

A physical problem statement is discussed as applies to simulation oftermogas dynamic processes in low thrust liquid-propellant rocket engines at non-ideal conditions. The statement is based on experimental results obtained by the author of the paper. Appropriate mathematical model is discussed as well as a numerical algorithm and its software implementation to solve the model. Validation results are presented to show adequacy of the model.
