Abstract


Energy saving and environment protecting are important issues about reasonable energyuse. Facing the situations, which the low level of energy use leads to the high level of energyconsumption and the pollution of oxynitride is more and more serious, energy saving andenvironment protecting receive significant attention day by day in our country.Firstly, this paper conducts the pulse combustion experiment which is researched throughtopic background, basic theory, FLUENT simulation and experiment. By numericalsimulation, we can analyze the temperature distribution and oxynitride concentration in thecombustor,by the experiment, we can obtain the heat efficiency and output of oxynitride underdifferent heating load. On the other hand, we can know when heating load changes between10kW-18kW, frequency is between18kW-22kW which can guarantee the pulse combustionnormal operation in the high heat efficiency and lower oxynitride concentration.In this paper, the pulse combustion is based on fluidic oscillating technology. Sooscillating frequency is bound up with pulse combustion frequency. By optimizing thestructure which length of feedback loop is changed, according to numerical simulation andexperimental study, analyze flow rate, frequency, Reynolds number, Strouhal number.Numerical simulation and experimental study prove that oscillating frequency and volumeflow have strongly linearity relation for different length of feedback loop of fluidicoscillator.And if volume flow is constant, oscillating frequency gradually decreases when thelength of feedback loop increases.Finally, some issues which are related with fluidicoscillating technology are researched in this article.
