Research On Motion Characteristics And Their Application Of Inhalant Particle In Rectangle Channel

In order to solve the deposition of graphite dust,which is generated in the process of fuel cycle of the ball,with their own and other graphite components generated by friction in high temperature gas cooled reactor,as well as the pollution control problem generated by the particulate matter from combustion source,flow of gas-solid,on the conditions of isothermal and variable-temperature,is simulated by FLUENT software, on this basis to discuss the law,which is that the turbulent deposition efficiency, thermophoresis deposition efficiency and total efficiency are influenced by the diameter and temperature difference.Compared with the other formula commonly,compucation results are of better accuracy.The process of graphite dust generated in high temperature gas cooled reactor is researched,graphite dust deposition is calculated in pipeline by compiling Fortran program,so high temeperature gas reactor is safe.The results provide foundation to improve the deposition efficiency by thermophoresis,thus further remove inhaled particulate matter.
