PURPOSE:To shorten a preheating time to a large extent and to reduce the thermal shock to a transducer, by transmitting the heat of a high temp. liquid to the transducer through a heating medium and a highly heat-conductive liquid. CONSTITUTION:Prior to the separation operation of a control ...
Although the detailed kinetics of the liquid phase decomposition of HMX have been reported [15,16], some previous studies used the global condensed phase kinetics of HMX/GAP for combustion process modeling [6,13,14] because the former did not match the HMX/GAP combustion process modeling. ...
The liquid phase fraction is about 20%–35% at the reaction temperature; and when the preheating temperature is 400 °C, the resultants have a porosity of 70%. When preheating is conducted between 400 °C and close to 600 °C, the pores in the resultants are still spheric but no longer...
High Temperature Aims and scope A. A. Avdeev 34 Accesses Explore all metrics Abstract This paper studies the stability of boiling shock formed when limiting (near spinodal) superheatliquid superheat is reached in a flow. In these conditions the boiling shock is always accompanied by oscillations ...
Taking the hafnium diboride ceramic as an example, the effects of heating rate, cooling rate, thermal shock initial temperature, and external constraint on the thermal shock resistance (TSR) of ultra-high temperature ceramics (UHTCs) were studied through numerical simulation in this paper. The resu...

Under the action of high temperature, granite gives rise to thermal cracking or thermal shock. The change in mineral composition changes the physical and mechanical properties of the rock to a certain extent. This is similar to the result reported by Sun25. After the heat treatment, the rock ...

2.1.3 Thermal conductivity of high-temperature PCMs Thermal conductivity is a measure of how well PCMs conduct heat. High-temperature PCMs with high thermal conductivity can accelerate the rate at which energy acts on the entire material, improving the thermal energy usage efficiency while lowering ...
