Formation of vortex structures in channels with mass injection and their interaction with surfaces in solid-fuel rocket engines

Numerical Simulation of Intrachamber Processes in the Power Plant

“…Boundary conditions for (6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22) equation systems are given in Table 1.…”

“…To approximate the equations of conservation (6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22) in space, the method of control volumes [1] was used. The partitioning of the calculated area in space was performed using prismatic elements (hexagons) with a total number of 1,480,000 elements [30].…”

“…Mathematical modeling of intrachamber processes in a power plant is considered in [14][15][16][17][18][19][20][21]. However, they lack practically useful criteria equations.…”

“…However, they lack practically useful criteria equations. In [13][14][15][16][17][18][19][20], it is shown that the spatial flow in the CC and PV is characterized by the presence of vortex structures. Heat exchange processes in different layouts of PP are studied in [15][16][17], but they do not provide criteria relations, and there is no assessment of the applicability for equations [1][2][3][4][5][6][7].…”

“…The application of mathematical modeling methods to study the heat exchange processes in individual structures of PP is considered in [10][11][12][13][14][15][16][17][18][19][20]. In [10][11][12][13][14][15][18][19][20]22], the features of the flow structure in the pre-nozzle volume of CC PP with a recessed nozzle are shown, but there are no assessments of heat exchange near the surface of the recessed nozzle. Heat exchange processes in CC for various PP layouts are studied in [10,12,[21][22][23].…”
