The results of the comprehensive numerical analysis for dynamics of intrachamber processes that appear at nozzleless solid propellant rocket engine (SPRE) actuation are presented. A complete cycle of rocket engine operation is analyzed. We solve a conjugate problem involving the igniter actuation; heating, ignition and following combustion of a solid propellant charge; a combustion product flow in the combustion chamber; depressurization of the combustion chamber, and the subsequent motion of the rocket engine blank; variation of the combustion surface geometry at the expense of the gradual and nonuniform burnout of solid propellant web. © 2013 Allerton Press, Inc.

Numerical studies of gas-hydrodynamic processes in a perforated exhaust duct are carried out. The distributions of velocity and temperature fields are obtained for different design of exhaust duct. The thermal effect of hot gas on the exhaust duct walls is analyzed. © 2014 Allerton Press, Inc. Source

The experience gained in structural modifying the low-pressure drop gas turbine engine fuel atomizer with two air nozzles is presented. The volume of fluid (VOF) approach is used for analyzing the two-phase flows to describe the numerical analysis of atomization quality. The base design and the design based on numerical analysis are compared by using a full-scale experiment. © 2014 Allerton Press, Inc. Source
