The common solid-liquid phase change, liquid-gas phase change and solid-gas phase change are all attributed to the first order transition. For example, when ice melts into water at the same temperature, it needs to absorb heat and its volume becomes smaller so that this phase change also ...
A process for the nitrilation of a fatty acid or of a fatty acid ester, which is optionally unsaturated, by reacting the fatty acid or fatty acid ester with ammonia in a reactor operating continuously in the gas phase or in the mixed gas-liquid phase in a temperature range of from 180...
Examples would be liberation of a gas from a liquid-phase reaction or the formation of a precipitate in a fluid-phase reaction. 例如液相反应中气体的释放,或流动相反应中沉淀的生成。 blog.sina.com.cn 8. Just as in vapor-phase removal, the first step in liquid-phase removal is to orient th...
Method of interaction in gas-to-liquid and liquid-to-liquid systems consists in delivery of continuous and dispersed phases from confuser ends of phase contacting tubes. Volumetric flow rate of heterogeneous medium fed through each tube is related to volume of each confuser-diffuser member according...
The straight line corresponds to the liquid-phase, while the curves correspond to the gas phase. The liquid phase lines are above the gas phase lines, which reflects the characteristic that alcohol is more volatile than water. The maximum value ofpis the vapor pressure of alcohol, the minimum...
Gas/liquid phase changes produce large volume changes in working fluids. These volume changes are used as the driving power sources in actuators such as micro-pumps and valves. Most of these actuators are utilized in ordinary temperature environments. However, the temperature range in which the pha...
Solid–liquid–gas reactions are ubiquitous and are encountered in both nature and industrial processes1,2,3,4. A comprehensive description of gas transport in liquid and following reactions at the solid–liquid–gas interface, which is substantial in regard to achieving enhanced triple-phase reaction...
Flow pattern maps using gas and liquid superficial velocities as coordinates and the correlations to describe flow pattern transition for the newly proposed microchannel test sections are obtained, respectively. 展开 关键词: Two-phase Flow pattern Microchannel Reentrant cavity ...
