N2 - Numerical modeling of jet flows of nitrogen expanding through a nozzle into a vacuum chamber has been carried out. A hybrid method is used in computations: continuum approach for the nozzle flow and for the jet near field and kinetic approach for the jet far field. The approach makes it possible to perform computations effectively in the near field and to take into account thermal non-equilibrium and rarefaction effects in the far field. The approach is applied to simulate jets produced in the LEMPUS-2 experimental facility. The experiments are carried out under the following conditions: stagnation pressure, 30 kPa and 20 kPa; background pressure in the vacuum chamber, 1 and 0.16 Pa; nozzle diameters, 1.2 and 0.5 mm, respectively, to obtain data for comparison. In the first case, the formation of a Mach disk occurs; in the second one, shock waves are not formed; the jet expands close to outflow into vacuum.
