Numerical simulations of mixing under supercritical pressures of a shear coaxial injector using a high-order method: effect of outer jet temperature
University of Tokyo 2-11-16 Yayoi, Bunkyo, Tokyo 113-8656, Japan
A three-dimensional (3D) simulation of N2/H2 mixing for a coaxial injector under a supercritical pressure of 10 MPa is conducted using a highorder numerical method. Two outer H2 jets with injection temperatures of approximately 52 and 462 K are applied while an inner N2 jet with an injection temperature of approximately 97 K is applied. The mean and fluctuation properties and instantaneous flow fields are discussed in order to characterize the detailed mixing features for the two injection conditions. A clear dependence of dense-core length on the momentum flux ratio is also demonstrated.
