Contribution of Mach number on the evolution of Richtmyer-Meshkov instability induced by shock-accelerated square light bubble [PDF]

open access: yesPhys. Rev. Fluids 6, 104001 (2021), 2021
The Richtmyer-Meshkov (RM) instability has long been an interesting subject due to its fundamental significance in scientific research, as well as its crucial role in engineering applications. In this study, the contribution of shock Mach number on the evolution of the RM instability induced by a shock-accelerated square light bubble is investigated ...

Flutter analysis of tapered composite fins: Analysis and experiment [PDF]

open access: yesFME Transactions, 2022
In the present work, the aeroelastic stability of tapered composite plates is investigated. Existing flutter models, based on the typical section approach, are reviewed for quasi-steady and unsteady low Mach number axial flows and modified for the thin ...

A low Mach number solver: Enhancing applicability [PDF]

open access: yesJournal of Computational Physics, 2013
In astrophysics and meteorology there exist numerous situations where flows exhibit small velocities compared to the sound speed. To overcome the stringent timestep restrictions posed by the predominantly used explicit methods for integration in time the Euler (or Navier-Stokes) equations are usually replaced by modified versions.

Low Mach Number Flows and Combustion [PDF]

open access: yesSIAM Journal on Mathematical Analysis, 2006
We prove uniform existence results for the full Navier-Stokes equations for time intervals which are independent of the Mach number, the Reynolds number and the P clet number. We consider general equations of state and we give an application for the low Mach number limit combustion problem introduced by Majda.

Modelling interactions between waves and diffused interfaces

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 95, Issue 2, Page 215-241, February 2023., 2023
When simulating multiphase compressible flows using the diffuse‐interface methods, important issues arise during the interaction of waves with diffused interfaces. A solution is to use a pressure‐disequilibrium model with finite, instead of infinite, pressure‐relaxation rate.
