Effective Hybrid Optimization Strategy in the Configuration of Aircraft Pressure Refuel Pipeline Orifices;

The Application of Genetic Algorithms to the Optimum Configuration of Aircraft Pressure Refuel Pipeline Orifices;

Study on two-phase flow characteristics of the orifice in MSF process;

To solve the problem of pipes vibration of large-sized compressor in ammonia plant, orifice plates are installed after thorough analysis of the causes of vibration, effectively solved the problem.

Applying throttle orifice to power plants;

With applying the throttle orifice in power plant,the thermodynamic processes and the physical phenomena is detailed for the steam water flowing through the throttle orifice,and after analysing the reason,this paper described how to calculate the orifice stages number and the orifice diameter,and in the end,the concrete application cases are presented.

7 of ultra-supercritical unit in fourth-phase project of Hudian Zhou’xian Power Plant have been analysed, it is believed that the main causes resulting in tube-burst are as follows: blockage of throttle orifice in the inlet of tubes, making the passage section to be reduced, the flow rate of steam to be decreased, the cooling effect to be bad, and the tubes to be overheated.

Design of configuration parameters of externally pressurized spherical gas bearings with orifice compensation;
