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.

Design and Implement of CTP Control System and USB Data Interface Circuit;

Computer -to -Plate ( CTP) is a machine which adapts Light Mechanical and Electrical Integration Technique to image plates digitally, and it is widely used in large modern printing enterprises.
