    Mathematical Modelling of Shock Wave Reflection from a Heat-Conducting Wall [Articol]
    (2024) Secrieru, Grigore
    In this work, on the basis of the model of the Navier-Stokes equations, a study of the dynamics of the flow, which arises in the process of reflection of a normally incident shock wave from a heat-conducting wall, is carried out. At the weak intensity of the shock wave and moderate jump in the initial temperatures of gas and wall, analytical expressions for the perturbation of gas parameters, describing the main characteristic features of the reflected flow, are obtained. This allows us to evaluate the influence of viscosity, thermal conductivity and other physical effects on the formation of dissipative and ideal non-viscous and non-heat-conducting zones in the region of the arising flow.
