On the Efficacy of Turbulence Modelling for Sloshing
Applied Sciences, 2022 As part of a wider project to understand the applicability of utilising slosh-based damping for wing-like structures, simulations of partially filled tanks subjected to harmonically oscillating and vertical motion are presented.

On the dependence of third- and fourth-order moments on stability in the turbulent boundary layer [PDF]
, 2005 In this short review it is suggested that the relationship between third- and fourth-order moments of turbulence in the atmospheric boundary layer depends on stability.

Simulation of hydrogen auto-ignition in a turbulent co-flow of heated air with LES and CMC approach [PDF]
, 2011 Large-Eddy Simulations (LES) with the first order Conditional Moment Closure (CMC) approach of a nitrogen-diluted hydrogen jet, igniting in a turbulent co-flowing hot air stream, are discussed. A detailed mechanism (nine species, 19 reactions) is used to

Mathematical Methodology and Metallurgical Application of Turbulence Modelling: A Review
Metals, 2021 This paper focusses on three main numerical methods, i.e., the Reynolds-Averaged Navier-Stokes (RANS), Large Eddy Simulation (LES), and Direct Numerical Simulation (DNS) methods. The formulation and variation of different RANS methods are evaluated.

Modelling of natural and bypass transition in aerodynamics
EPJ Web of Conferences, 2014 Most of transition models are proposed for modelling of the bypass transition common in the internal aerodynamics especially in turbomachinery where free stream turbulence is the dominant parameter affecting the transition onset.

Results for a turbulent system with unbounded viscosities: weak formulations, existence of solutions, boundedness, smoothness' [PDF]
, 2007 We consider a circulation system arising in turbulence modelling in fluid dynamics with unbounded eddy viscosities. Various notions of weak solutions are considered and compared. We establish existence and regularity results.

Anisotropic Organised Eddy Simulation for the prediction of non-equilibrium turbulent flows around bodies [PDF]
, 2008 The unsteady turbulent flow around bodies at high Reynolds number is predicted by an anisotropic eddy-viscosity model in the context of the Organised Eddy Simulation (OES).
