O₂?¹?_g? Yield Detection In Liquid Phase And Fluid Dynamics Simulation Of SOG

As a kind of high-energy clean green energy, Chemical Oxygen Iodine Laser (COIL) has great economic and social benefits. Singlet oxygen generator is the direct source of the chemical oxygen iodine laser energy, the size of the singlet oxygen production rate is directly related to the use of chemical laser. Therefore, we need to detect theory of singlet oxygen production rate, reducing the quenching rate, and its practical application in singlet oxygen generator.Determination of singlet oxygen production rate of the gas has built up, but relative production rate is relatively low in the gas phase, we need to determine singlet oxygen production rate of the reaction between chlorine and alkaline hydrogen peroxide in the reactor's, in order to further determine the actual yield of singlet oxygen in the liquid phase. With the analysis method matured, and accurate analytical instruments and popularization, that laid a certain condition for the determination of liquid rate; Liquid rate points to further determine two phase reaction mechanism and reaction kinetics equation, at the same time to reduce the singlet oxygen quenching rate; With the CFD simulation matured, it can reflect fluid flow of the container. The application of the reaction mechanism and kinetics equations of experiment in numerical simulation, that plays an important role in the further study of the COIL.This article is based on the actual project by researching the literature, to determine reasonably singlet oxygen detection system, and experimental device needed to set. Determine the way of experimental detection analysis, mainly includes the determination of H2O2 concentration, concentration of Cl" and the singlet oxygen production rate calculation method, etc.; I analyze experiment device that is set up, by observing the experiment phenomenon, I can found that reaction equation is basic in line with the literature results; And I solve the problem in the process of experiment, then determine to do reference solution in the solution after the reaction, the experiment operating temperature is adjustable to 0?; Acidic conditions for experiments as operating conditions; And I investigate thatH2O2, HNO3, NaClO, DMFu respectively affect experiment that DMFu capture singlet oxygen; Finally I summarizes the experimental results, evaluate the experiment scheme and put forward new ideas.The main purpose of the experiment is to its application in singlet oxygen generator, so I need to simulate the fluid flow condition of fluid mechanics within singlet oxygen generator. In view of the present commonly used jet singlet oxygen generator, using computational fluid dynamics, the 2-d geometric model and the corresponding mathematical model is set up, set the initial boundary condition, the gas liquid two phase fluid flow situation in the reactor were analyzed. Through the analysis shows that the reactor internal condition of gas phase and liquid phase fluid, temperature and pressure distribution inside the reactor, that provides a good foundation in order to further simulation.In this article, the liquid phase detection system of singlet oxygen production rate put a solid foundation for further modify the experiment scheme, and completing the singlet oxygen middle rate determination to; Fluid flow analysis in the reactor, which is beneficial to modify the application of singlet oxygen reactor.
