Struts as an important structure in the combustion chamber of hypersonic flight vehicles to inject fuel into main flow face a severe thermal environment. Transpiration cooling is considered potential method provide protection for struts. This paper presents numerical investigation on transpiration strut based Darcy–Forchheimer model and local non-equilibrium analyzes mechanism cooling. A coolan...

We study the dissipative evolution of (0+1)-dimensionally expanding media with Bjorken symmetry using Boltzmann equation for massive particles in relaxation-time approximation. Breaking conformal by a mass induces non-zero bulk viscous pressure medium. It is shown that even small (in units local temperature) drastically modifies well-known attractor shear Reynolds number previously observed mas...

In this work, a new mathematical model of thermoelasticity theory has been considered in the context of a new consideration of heat conduction with fractional order theory. A functionally graded isotropic unbounded medium is considered subjected to a periodically varying heat source in the context of space-time non-local generalization of three-phase-lag thermoelastic model and Green-Naghdi mod...

The thermodynamic model of ultrathin lubricant film melting, confined between two atomically-flat solid surfaces, is built using the Landau phase transition approach. Non-equilibrium entropy is introduced describing the part of thermal motion conditioned by non-equilibrium and non-homogeneous character of the thermal distribution. The equilibrium entropy changes during the time of transition of...

7 Generation of entropy and transfer of heat during forced convection of a nanofluid through a partially-filled 8 porous channel are investigated theoretically. The problem includes a fully developed flow in a channel with a 9 central porous insert and under constant heat flux boundary condition. The system is assumed to be under local 10 thermal non-equilibrium and the solid and nanofluid phas...
