High-temperature thermal physics and problems of thermal protection

The experimental investigation of the ignition petrol mechanism at high temperature metal single particles

“…1), providing stable temperature of the working volume (1400 K) for a prolonged time. Measurement error of the initial temperature of the particles, as measured by the method of [7], did not exceed 1-3%.…”

Mathematical Modeling of the Heat Transfer Process in Porous Cooling Systems Under Influence Low Energy Disturbances

“…Transpiration cooling systems are widely used in engineering applications: evaporation systems, filters, thermal protection elements of flight vehicles [4][5][6][7]. The operation of such systems may be accompanied by some perturbations, such as acoustic oscillations, wall vibrations, pressure fluctuations and turbulent noises.…”

“…In curtain zone 2, we use the formula from [10] in the form of the Mugalev's modification, which takes into account the effect on injection on the heat flow [4] ) )( 1 (…”

“…The flow rate of the coolant gas will be determined from the combined solution of the steady-state equation of continuity and the nonlinear Darcy law [4,14]. The fact is that high mass rates w v) (U (Re > 10) are associated with turbulent filtration behavior [14], which is characterized by the quadratic dependence of the pressure differential on the rate.…”

Determination of thermophysical characteristics of materials at thermal effect of constant power

“…Solution to the problems of thermal design and development of optimal parameters of heat-protection systems is inseparable from thermal fields calculation in the structures and requires knowledge of thermophysical characteristics (TPC) of materials [1]. At present, theoretical models for calculation of TPC of structurally complex composite materials are not accurate enough, therefore, main source of information on their properties is a thermophysical experiment [2,3].…”
