Two-dimensional over-expanded jet flow parameters in supersonic nozzle lip vicinity

Supercomputer predictive modeling for ensuring space flight safety

“…However, on moving away from the nozzle one could notice diffusion of fuel and oxidant concentration and their mutual penetration, which is characteristic for a kinetic regime. Comparison of nozzle flows with available analytical solutions demonstrated good coincidence [33]. Fig.…”

Correction thruster development based on high-current surface discharge in vacuum

“…Next, using the data obtained in [1,13,14,15] and taking ΔU¼5 kV ions accelerating field at an electric field intensity of Е¼5 kV/mm, the EPT operational data are the following: ion current intensity limit j¼330 mA/cm 2 , ion flow velocity V flow ¼86 km/s, specific impulse value J¼8600 s, and traction value F¼ 140 mN. The obtained assessed values of j, V flow , J, and F correspond or exceed the values of those characteristics known in the best current EPT prototypes.…”

Theoretical and experimental investigations of the interaction of hot gases with liquid in closed volume

“…The equilibrium and non-equilibrium boundary conditions on the surface of a burning droplet are considered in [15][16][17]. The peculiarities of over-expanded jet flows in vacuum accounting for possible chemical reactions are investigated in [18][19][20][21].…”
