High-enthalpy gas streams in a real engine or wind tunnel will contain some trace gases; however, this is often ignored many studies. To investigate transverse fuel-jet mixing and combustion characteristics high-enthalpy inflow with trace-gas species, large-eddy simulations based on the HyShot II configuration have been adopted verified. It was found that amount of atomic oxygen (O) nitrous oxide has direct significance ignition delay times can, therefore, influence overall flame...
In this study, combustion processes in a cavity-based scramjet combustor are experimentally studied based on the inflow conditions of different stagnation pressures (, 1.3, and 1.6 MPa), which correspond to Mach 6 flight at trajectories dynamic 0.25, 0.34, 0.43 atm, respectively. Three modes identified according flame distribution, flowfield structure, wall pressure. Cases same equivalence ratio mode with selected compare characteristics. For each condition, intensity, coherence between...
It has been found that the static pressure distribution along axial direction of liquid kerosene is lower than gaseous under same flow condition and overall equivalent ratio from previous studies. To further investigate this phenomenon, a compressible two-phase parallel simulation method utilized to analyze mixing combustion characteristics jets in cavity-based supersonic combustor. The numerical results are consistent with experiments demonstrate injection leads cavity shear layer dives...
Previous studies have found that the difference in combustion characteristics of gaseous and liquid kerosene injection supersonic combustor is sensitive to equivalent ratio. In this paper, previous work extended a high ratio gain deeper understanding effect states on performance via numerical computation. The simulation results match well with experiments demonstrate due different jet structures, cavity shear layer penetrates deeply into cavity, forming two recirculation zones therein. As...
Though the k–ω shear-stress transport (SST) turbulence model is widely used, it developed based on incompressible flow and analysis of simple characteristics such as boundary layer free shear flows. Due to lack comprehensive consideration important structures, shock wave highly compressible zones, SST has inherent limitations in describing supersonic A multi-physics improvement strategy proposed improve prediction accuracy for This leverages shock/turbulent shock/compressibility functions...
Efficient 2D membranes play a critical role in water purification and desalination. However, most membranes, such as graphene oxide (GO) tend to swell or disintegrate liquid, making precise ionic sieving tough challenge. Herein, the fabrication of polyoxometalate clusters (PW
To reveal the effects of confinement and curvature on jet mixing in a supersonic cross-flow, large eddy simulations were conducted to study cross-flow channel pipe at Mach number 2.7. The comparison was based an equal friction number, Reynolds Prandtl number. synthetic model utilized generate inflow turbulent boundary layer. Our shows major counter-rotating vortex pair (CVP) higher than channel, while trailing CVP larger appeared within recirculating flow. had stronger shock train due pipe....
The design and synthesis of two-dimensional membranes with ultra-high permeability, selectivity, antifouling properties have been a significant challenge. Herein, we propose facile approach to modular polyoxometalate-intercalated layered double hydroxide using charge-driven self-assembly process. resultant MgAl-SiW12 membrane shows 4 times higher water permeance (>130 L m−2 h−1 bar−1) than that its MgAl-NO3 precursor. Excellent retention >99% for Congo red Evans blue is achieved by the...
