TURBULENT MIXING IN MULTI-NOZZLE INJECTION TUBULAR MIXER

抄録

Turbulent mixing in this type mixer is experimentally investigated. Probability density distribution function of ''c is measured by using digital counter and proves to be normally distributed. This fact affirms the basis of Toor''s theory. Concentration spectrum has a narrow -5/3 power region, Toor''s theory concerning the relation between concentration fluctuation and conversion of very rapid reaction is experimentally proved. Initial mixing rate is studied on the basis of it. Dependence of the mixing time constant on U, a, d_N and D_m are measured. Their effects are generally explained by modified Corrsin''s equation.
