چکیده
An unsteady numerical simulation method was used in order to explore more efficient atomization methods for liquid fuel scramjet combustors and study the influence of different shock wave incident positions on characteristics kerosene crossflow. The wedge compression surface generate wave, position jet controlled by changing angle surface. inlet Mach number 2.01; total temperature 300 K, momentum ratio 12. research results show that as moves upstream, penetration depth is essentially unchanged, but inner edge trajectory closer wall. Because affects Kelvin–Helmholtz instability jet, unsteadiness root strengthened, downstream weakened. stability particle-size distribution are, thus, realized quickly. reduces Sauter mean diameter section makes droplet uniform. along flow direction increase first then decrease. changes are determined reflux region, transport, pressure caused wave.

High-fidelity Simulation of High Density-Ratio Liquid Jet Atomization in Crossflow with Experimental Validation
Liquid jet atomization in cross-flowing gas is a critical phenomenon in the fuel preparation process and controls combustor efficiency and emissions. Quantitative experimental studies of atomization have been rare due to limited optical access to the near-field dense spray region. High fidelity multiphase flow simulation has shown promise as an alternative approach for scrutinizing the complex ...
متن کاملPeriodic Wave Shock solutions of Burgers equations
In this paper we investigate the exact peroidic wave shock solutions of the Burgers equations. Our purpose is to describe the asymptotic behavior of the solution in the cauchy problem for viscid equation with small parametr ε and to discuss in particular the case of periodic wave shock. We show that the solution of this problem approaches the shock type solution for the cauchy problem of the in...

15 صفحه اولDetailed Numerical Simulations of the Primary Atomization of a Turbulent Liquid Jet in Crossflow
This paper presents numerical simulation results of the primary atomization of a turbulent liquid jet injected into a gaseous crossflow. Simulations are performed using the balanced force refined level set grid method. The phase interface during the initial breakup phase is tracked by a level set method on a separate refined grid. A balanced force finite volume algorithm together with an interf...
