Three-dimensional wall heating elements effect on the instability in zero pressure gradient supersonic boundary layers

Z Bi, P Wang, J Xu, J Liu - Physics of Fluids, 2023 - pubs.aip.org
The streaky boundary layers have very important roles in laminar-turbulent transition.
Streaks of appropriate size can influence stabilities in boundary layers. In this paper, the …

On the grid dependence of hydrodynamic stability analysis in solid rocket motors

Y Li, Z Wang, P Liu - Physics of Fluids, 2020 - pubs.aip.org
In this numerical study, we investigate the grid dependence of the Chebyshev collocation
algorithm for flow stability analysis of solid rocket motors. Conventional analyses tend to …

Efficient Solution Approach for Internal Ballistics

RJ Hartfield, GA DiMaggio, J Majdalani - AIAA Propulsion and Energy …, 2020 - arc.aiaa.org
This paper presents an efficient approach to solve for the internal ballistics in a solid rocket
motor. Legacy methods consist primarily of lower-order (one-dimensional) and higher-order …

Global thermoacoustic oscillations in a thermally driven pulse tube

S Kumar, A Samanta - Theoretical and Computational Fluid Dynamics, 2019 - Springer
We obtain linearized, BiGlobal thermoacoustic solutions in a pulse tube driven via an
imposed mean temperature gradient. Here, the pulse tube is treated as a key unit of a …
