Review on Creep Phenomenon and Its Model in Aircraft Engines
International Journal of Aerospace Engineering, Volume 2023, Issue 1, 2023., 2023 The aircraft is subjected to high‐temperature and high‐pressure conditions during flight, which renders it susceptible to the occurrence of creep phenomenon. Several academics have conducted extensive research on this issue. This research paper provides a comprehensive overview of the existing literature on creep phenomena in aircraft engines.

Numerical Study on the Non-Oscillatory Unstarted Flow in a Scramjet Inlet-Isolator Model
Aerospace, 2022 For successful scramjet engine operations, it is important to understand the mechanism of the inlet unstart phenomenon. Among various unstarted flow patterns in hypersonic inlets, the mechanism of low-amplitude oscillatory unstarted flow is still unclear.

International Journal of Aerospace Engineering, Volume 2023, Issue 1, 2023., 2023 Liquid oxygen chill‐down in a straight horizontal pipe was studied experimentally. The effect of the entrance corner was excluded, and much denser wall temperature sensors along the pipe have been set compared to the present studies. In this way, the chill‐down process, as well as the development of the flow pattern, has been drawn for every test. As a

Numerical Investigation of Contact Burning in an Air‐Breathing Continuous Rotating Detonation Engine
International Journal of Aerospace Engineering, Volume 2022, Issue 1, 2022., 2022 Three‐dimensional (3D) numerical simulations of a continuous rotating detonation engine are carried out with an unsteady Reynolds‐averaged Navier‐Stokes solver. The second‐order upwind advection upstream splitting method and second‐order Runge‐Kutta method are used to discretize space and time terms, and detailed 9‐species 19‐step hydrogen‐oxygen ...

Numerical Study on Effects of Arrayed Pulsed Energy Depositions on a Supersonic Combustor
International Journal of Aerospace Engineering, Volume 2022, Issue 1, 2022., 2022 This paper proposes a method to improve the mixing efficiency of a supersonic combustor by using arrayed pulsed energy depositions, and this method is verified by a numerical simulation. In the simulation, the Navier‐Stokes equations with an energy source are solved to simulate the effects of energy depositions in various distributions on the fuel ...
