Model of steam-water two-phase flow lifting-pressure mechanism based on direct contact condensation;

A one-dimensional theory model based on direct contact condensation is presented to analyze the lifting pressure characteristics of steam-water injector, and some key issues, such as inter-phase mass transfer computed by the average condensation heat transfer coefficient and phase volume fraction determined by steam plume, are discussed in detail.

Model calculation and analysis of heat and mass transfer of air and water in a direct contact forward flow;

The submerged combustion evaporator is a high-efficiency equipment using direct contact heat transfer between superheated bubbles and the liquid.

In order to ensure work properly of residual current circuit breakers, the necessity to select the operating characteristic of the residual current circuit-breakers reasonably was described, that is to select the different operating current and different breaking time according to indirect contact protection and direct contact protection, or the fire protection due to electric fault.

Exergy analysis of refrigeration cycle of a direct-contact ice storage system;

the application of complicated energy analysis method with the first law of energetics and exergy analysis to direct-contact and ice-on-coil storage system is investigated in order to assess efficiencies of the system.

It was proposed that,bortex shear force and inertial centrifugal force were the main driven force causing particle contact flocculation,and the vortex shear force was the dominant kinetic factor;the floc diameter and density was controlled by transition zone of the turbulent flow;meanwhile,the technology for improving flocculation efficiency was also discussed.

Taking the water treatment plant of Jiujiang Chemical Fiber Factory as an example,the paper introduces the reconstruction of pulse clarifier by using a contact flocculation inclined-tube settling technology.
