Large-eddy simulations of dense-gas dispersion within a high-Reynolds number turbulent boundary layer
(2017)
Large-eddy simulations of flows over a backward-facing step with release of four different gases with increasing densities have been performed. The results have been analysed with particular emphasis on the part of the ...
Computing turbulence structure tensors in plane channel flow
(2016)
This paper is concerned with the computation of turbulence structure tensors in plane channel flow. It has been pointed out that the previously computed turbulence structure tensors, for this configuration, used an ...
Linear motion of multiple superposed viscous fluids
(2019-04-16)
In this paper the small-amplitude motion of multiple superposed viscous fluids is studied as a linearized initial-value problem. The analysis results in a closed set of equations for the Laplace transformed amplitudes of ...
Single-point structure tensors in turbulent channel flows with smooth and wavy walls
(2019-10-06)
A long-standing problem in turbulence modeling is that the Reynolds stress tensor alone is not necessarily sufficient to characterize the transient and nonequilibrium behaviors of turbulence under arbitrary mean deformation ...
Particle-resolved simulations of shock-induced flow through particle clouds at different Reynolds numbers
(2020-01-27)
This study investigates the Reynolds-number dependence of shock-induced flow through stationary particle clouds at 10% volume fraction, using ensemble-averaged results from three-dimensional particle-resolved large eddy ...
Performance of drag force models for shock-accelerated flow in dense particle suspensions
(2021-04)
Models for prediction of drag forces within a particle cloud following shock-acceleration are evaluated with the aid of results from particle-resolved simulations in order to quantify how much the disturbances introduced ...
Comprehensive quasi-steady force correlations for compressible flow through random particle suspensions
(2023-04-26)
Models for quasi-steady drag, quasi-steady drag variation, and transverse forces for compressible flows through random, fixed, particle suspensions are presented. Correlations are formulated using drag force measurements ...
Computational analysis of shock-induced flow through stationary particle clouds
(2019-03-22)
We investigate the shock-induced flow through random particle arrays using particle-resolved Large Eddy Simulations for different incident shock wave Mach numbers, particle volume fractions and particle sizes. We analyze ...
