“…After reviewing the literature on studies that dealt with shock waves in gas flows, we did not find studies related to flows with nanoparticles. But there are quite large developments in the study of shock waves in dusty flows [18][19][20][21][22]. This is the closest set of problems to this study.…”

“…Based on the processed data, the law of resistance was obtained, which describes the acceleration of a particle in the relaxation zone. Solutions were obtained on the basis of which unsteady changes in heat transfer parameters, the effects of an increase in the mass concentration of solid particles in a mixture and the ratio of the density of solid particles to the initial gas density on the flow variables in the region behind the shock wave were studied in [22].…”

The paper focuses on the analytical analysis of the propagation of a normal shock wave in an adiabatic gas flow with nanoparticles. A modified Rankine–Hugoniot model was used for this purpose. A solution is obtained for the Rankine–Hugoniot conditions in a gas flow with different nanoparticle concentrations, which makes it possible to analyze the dynamics of variation of the parameters of this type of flow under a shock wave. The variation of velocity, pressure and entropy production of the adiabatic gas flow during a direct shock wave depending on the concentration of nanoparticles in the gas was depicted graphically. It was revealed that increasing the nanoparticle concentration to φ ~ 0.1 weakens the effect of the shock wave, and then, after passing the zone of minimum parameters, the intensity of the shock wave increases.
