There is currently great interest in replacing the harmful volatile hydrofluorocarbon fluids used refrigeration and air-conditioning with solid materials that display magnetocaloric, electrocaloric or mechanocaloric effects. However, field-driven thermal changes all of these caloric fall short respect to their fluid counterparts. Here we show plastic crystals neopentylglycol (CH3)2C(CH2OH)2 unprecedentedly large pressure-driven near room temperature due molecular reconfiguration, are...
Processes of heat, momentum, and concentration transport in a boundary layer nanofluid near flat wall were studied. The study was performed by means numerical analysis equations self-similar form. Self-similar forms these obtained based on symmetry properties (Lie groups). In doing so, dependence physical (viscosity, thermal conductivity, diffusion coefficient) nanofluids temperature taken into account. Effects the nano-particles velocity profiles, as well relative Nusselt numbers...
Heat, momentum, and mass transport in turbulent boundary layer nanofluid flow over a flat plate were investigated. Boundary equations reduced to self-similar forms solved numerically. The Lie group technique, which is based on the symmetry properties of governing equations, was used derive these equations. Turbulent viscosity predicted using mixing-length model. Also, dependences physical (viscosity, thermal conductivity, diffusion coefficients) concentration temperature accounted for....
This article theoretically investigates the interaction of a normal shock wave in flow with chemical reactions under high-temperature conditions. The main novelty work is that thermal effect modeled as function temperature. A modified Rankine–Hugoniot model for has been developed. It shown an exothermic reaction pressure jump increases increasing Arrhenius numbers. due to additional energy introduced into heat released during reaction. For endothermic reactions, opposite trend observed....
Symmetry transformation methods are widely used in fluid flow problems. One such method is renormalization group analysis. Renormalization to develop a macroscopic turbulence model for non-Newtonian fluids (Oldroyd-B type). This accounts the large-distance and large-time behavior of velocity correlations generated by momentum equation randomly stirred, incompressible does not account empirical constants. The aim this mathematical study was k-ε RNG For first time, using procedure, transport...
The article presents results of an analytical and numerical modeling electron fluid motion heat generation in a rectangular conductor at alternating electric potential. solution is based on the series expansion (Fourier method) double (method eigenfunction decomposition). lattice Boltzmann method (LBM). An for current was obtained. This enables estimating determining influence parameters characterizing dimensions, parameter M (phenomenological transport time describing momentum-nonconserving...
In a supersonic flow, disturbances of different parameters arise. These perturbations can have significant impact on the interaction flow with surface. When gas passes through shock wave, are transformed depending initial flow. Therefore, it is important to be able correctly assess intensity these transformations. this work, for first time, method has been proposed that allows us estimate dynamics variation when passing an oblique wave. The influence wave inclination angle β, Mach number,...
