Transition Between Regular Reflection and Mach Reflection in the Dual-Solution Domain [PDF]
, 2007 A study of the shock-reflection domain for steady flow is presented. Conditions defining boundaries between different possible shock-reflection solutions are given, and where possible, simple analytic expressions for these conditions are presented. A new,

An experimental validation of a nonlinear acoustic resistance model for an acoustically compact area contraction with steady mean flow [PDF]
JASA Express Letters, 2021 In a previously published paper, a model for the nonlinear acoustic response of an area contraction including bias flow was presented. The model's prediction for the zero-driving resistance grew progressively worse as the steady-flow Mach number ...

A low Mach number solver: Enhancing applicability [PDF]
Journal 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.

Sound radiation in turbulent channel flows [PDF]
, 2003 Lighthill’s acoustic analogy is formulated for turbulent channel flow with pressure as the acoustic variable, and integrated over the channel width to produce a two-dimensional inhomogeneous wave equation.

Comparative analysis of 2D simulations and isentropic equations for compressible flow in experimental nozzles [PDF]
INCAS Bulletin, 2023 Experimental studies for supersonic airflow in different supersonic nozzle geometries are recurrent, and the turbulence of the flow can be reproduced with the CFD tool by applying the RANS model and suitable turbulence models.

Modelling of natural convection flows with large temperature differences : a benchmark problem for low Mach number solvers. Part 1, Reference solutions [PDF]
, 2005 There are very few reference solutions in the literature on non-Boussinesq natural convection flows. We propose here a test case problem which extends the well-known De Vahl Davis differentially heated square cavity problem to the case of large ...
