Abstract
To investigate the mechanism of TUSOG(Transverse Uniform Singlet Oxygen Generator), a two-phase, chemistry reactive flows model is established to describe the physical and chemical performances of Cl2/He mixed gases which transversely travels through a falling BHP(KOH,H2O2,H2O) droplets field, and the relevant numerical simulation is carried out. In the gas-phase model equations, the mass source term is determined by drop-absorbed chlorine and released singlet oxygen due to chemical reaction between drops and chlorine. An assumption is made that the BHP drops have equal sizes and fall vertically in equal speeds. The set of gas-phase control equations is solved by SIMPLEC scheme. The computational results agree well with the test results provided by relevant reference. It is found, that chlorine utility and singlet oxygen yield decreases with increasement of gas inflow speed, and increases with increasement of the speeds of falling drops, and the absorption of chlorine mainly takes place in the upstream reactive region.
