High-fidelity large-eddy simulations (LESs) are performed to investigate aeroacoustic
characteristics of jets issuing from twin rectangular nozzles with an aspect ratio of 2: 1 at two …

The dynamic evolution of a highly underexpanded transient supersonic jet at the exit of a
pulse detonation engine is investigated via high-resolution time-resolved schlieren and …

Pulse detonation engines (PDEs) are advanced propulsion device for next generation of
propulsion systems. The PDE combustion processes are filling of fuel-oxidizer, combustion …

This study proposes a space-marching nozzle design method based on a modified CCW
relation and an auxiliary secondary injection technique for the shock-focusing detonation …

An investigation of shock diffraction through a non-quiescent background medium is
presented using both experimental and numerical techniques. Unlike diffracting shocks in …

An annular plenum is integrated downstream of six pulse detonation combustors arranged
in a canannular configuration. The primary purpose of the plenum is the mitigation of …

The operation of a multitube pulse detonation combustor (PDC) evokes undesirable
pressure fluctuations for a turbine downstream of the combustor. Pressure measurements in …

Fill fraction not only has a profound impact on the process of deflagration to detonation in
pulsed detonation engine, but also affects the propulsion performance in both flight and …

We investigate the effect of exit pressure history on the flow characteristics of
underexpanded transient jets. Using both experiments and numerical simulations, we study …

The pressure-sensitive paint (PSP) technique has shown superiorities in its large coverage
area capability and high spatial resolution. The process of the PSP technique usually …
