Numerical Simulation of Heat Transfer in Ozone Generation Using Coaxial Cylinders Dielectric Barrier Discharge
摘要
Abstract
In the process of ozone generation by dielectric barrier discharge（DBD）,most of electric energy is emitted in the form of heat energy.Moreover,the temperature of gas is one of the most important parameters which infect ozone productivity and concentration.Due to the restriction of study method and accuracy of detecting instrument,it is difficult to experimentally study energy transformation and heat transfer.Therefore,we analyzed the heat transfer of ozone discharge chamber via DBD through the method of numerical simulation.Meanwhile,the feasibility of the method was checked by experiment.The results of simulation show that the temperature of gas is gradually reduced from high-voltage electrode to glass dielectric,the mean temperature of gas rises rapidly along axial distance in a shot time then gradually drops,at the same time,the inlet temperature,flow of cooling water and the width of cooling water channel remarkably affect gas temperature.The results of study would provide scientific evidences for the control of gas temperature and the design of ozone generator.关键词
