However, thermal cycling seemed to compromise passivity; expansion and contraction during heating and cooling allowed oxygen penetration into the underlying metal in local regions, leading to transgranular crack-like features. Spallation of oxides was also observed. Post-exposure analysis of the oxide ...
At present, the main research direction is to transfer the external heat directly or indirectly to the working fluid in the expansion process, reduce the temperature difference caused by the expansion endothermic, improve the pressure ratio and output power density in the expansion process (Dib et ...

The volume expansion and contraction excite an oscillation motion of the liquid plugs and vapour bubbles in their wickless miniature channels. Through forced convection and phase-change, heat is transported from the evaporator to the condenser [5,6]. Continuous heating sustains the oscillation flow ...
Further adjustment of the Expansion correction factor and Contraction correction factor may be required. Refer to the Area Change (IL) and Sudden Area Change block pages to compare changes in the equations. Power in the contraction loss coefficient has been reformulated from 0.75 to...
Additionally, as the temperature of the glass article blank 101 and the mold 300 decrease, the glass article blank 101 and the mold 300 will reduce in size due to the respective coefficients of thermal expansion. However, because the glass article blank 101 and the mold 300 likely have ...
Operating on a thermodynamic cycle of isentropic compression, isothermal expansion, isentropic expansion and finally constant pressure cooling and contraction, an external heat engine utilizes a heat exchanger carrying heat from an external energy source to the working parts of the engine. Apparatus and ...
Upon cooling and heating, the cell parameters appeared to contract and expand accordingly. The thermal contraction and expansion of parameter a is considerably larger than that of b , which probably results from the weaker intra-chain interactions along the a -axis, which is perpendicular to the ...
