Endwall aerodynamic losses from turbine components within gas turbine engines

Propulsion and Power Research, 2017
A survey of research on aerodynamic loss investigations for turbine components of gas turbine engines is presented. Experimental and numerically predicted results are presented from investigations undertaken over the past 65 plus years.

Derivation of Lighthill’s Eighth Power Law of an Aeroacoustic Quadrupole in Acoustic Spacetime

Acoustics, 2020
Acoustic spacetime is a four-dimensional manifold analogue to the relativistic spacetime with the reference speed of light replaced by the speed of sound.

Aeroacoustic formulations for confined flows based on incompressible flow data

Acta Acustica, 2022
The hybrid aeroacoustic approach is an efficient way to address the issue of the disparity of scales in Computational AeroAcoustics (CAA) at low Mach numbers.

A Massively Parallel Hybrid Finite Volume/Finite Element Scheme for Computational Fluid Dynamics

Mathematics, 2021
In this paper, we propose a novel family of semi-implicit hybrid finite volume/finite element schemes for computational fluid dynamics (CFD), in particular for the approximate solution of the incompressible and compressible Navier-Stokes equations, as ...

Kinetic simulations of scrape-off layer physics in the DIII-D tokamak

Nuclear Materials and Energy, 2017
Simulations using the fully kinetic code XGCa were undertaken to explore the impact of kinetic effects on scrape-off layer (SOL) physics in DIII-D H-mode plasmas.

Numerical Investigation of Mach 2.5 Axisymmetric Turbulent Shock Wave Boundary Layer Interactions

Aerospace, 2023
Shock wave boundary layer interactions are common to both supersonic and hypersonic inlet flows. Wall-resolved implicit large-eddy simulations of a canonical Mach 2.5 axisymmetric shock wave boundary layer interaction experiment at Glenn Research Center ...

Stability analysis of the vectorial Lattice-Boltzmann method [PDF]

ESAIM: Proceedings and Surveys
We perform a stability analysis of the Vectorial Lattice-Boltzmann Method (VLBM). The VLBM has been introduced in [1–3, 9, 18]. It is a variant of the LBM with extended stability features: it allows handling compressible flows with shock waves, while the

Low Mach Number Modeling of Type Ia Supernovae

, 2005
We introduce a low Mach number equation set for the large-scale numerical simulation of carbon-oxygen white dwarfs experiencing a thermonuclear deflagration.

Modelling of phase transitions in granular flows

ESAIM: Proceedings and Surveys, 2017
We present in this work a system for unidimensional granular flows first mentioned in a paper of A. Lefebvre–Lepot and B. Maury (2011), which captures the transitions between compressible and incompressible phases.

Magnetospheric balance of solar wind dynamic pressure

Geophysical Research Letters, 2017
The magnetopause is the boundary established by pressure balance between the solar wind flow in the magnetosheath and the magnetosphere. Generally, this pressure balance is represented to be between the solar wind, the dynamic pressure, and the magnetic ...
