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.

Taking the potential caused by vertical sheet in the point source current field domain for example,based on programming with FORTRAN,the result is analyzed by the use of the above-mention two methods respectively,and comparison on accuracy based on the result is made to determine precision and availability of the analysis solution.
