Robust optimisation of the streamlined shape of a high-speed train in crosswind conditions

open access: yesEngineering Applications of Computational Fluid Mechanics, 2023
Traditional deterministic aerodynamic optimisation cannot consider environmental uncertainty, which may lead to sensitivity issues. The present study proposes a robust design framework for the aerodynamic optimisation of high-speed trains, which accounts

Aerodynamics and three-dimensional effect of a translating bristled wing at low Reynolds numbers

open access: yesScientific Reports, 2022
The smallest insects fly with bristled wings at very low Reynolds numbers (Re) and use the drag of the wings to provide the weight-supporting force and thrust.

Description of Vorticity by Grassmann Variables and an Extension to Supersymmetry [PDF]

open access: yes, 2000
In this paper, particle physics concepts are blended into a field theory for macroscopic phenomena: Fluid mechanics is enhanced by anticommuting Grassmann variables to describe vorticity, while an additional interaction for the Grassmann variables leads ...

Numerical Study of Formation of a Series of Bubbles from an Orifice by Applying Dynamic Contact Angle Model

open access: yesAdvances in Materials Science and Engineering, 2020
The dynamic contact angle model is applied in the formation process of a series of bubbles from Period-I regime to Period-II regime by using the VOF method on a 2D axisymmetric domain.

Integrable Supersymmetric Fluid Mechanics from Superstrings [PDF]

open access: yes, 2001
Following the construction of a model for the planar supersymmetric Chaplygin gas, supersymmetric fluid mechanics in (1+1)-dimensions is obtained from the light-cone parametrized Nambu-Goto superstring in (2+1)-dimensions.

Measurements of a single pulse impinging jet. A CFD reference

open access: yesEPJ Web of Conferences, 2014
This paper reports three sets of measurements of a single pulse impinging jet. The purpose is to serve as a reference for CFD validation. A gas injector generates a single pulse jet at Re ~90000.

Wall-Normal Variation of Spanwise Streak Spacing in Turbulent Boundary Layer With Low-to-Moderate Reynolds Number

open access: yesEntropy, 2018
Low-speed streaks in wall-bounded turbulence are the dominant structures in the near-wall turbulent self-sustaining cycle. Existing studies have well characterized their spanwise spacing in the buffer layer and below.

On the influence of turbulent kinetic energy level on accuracy of k − ε and LRR turbulence models [PDF]

open access: yesTheoretical and Applied Mechanics, 2018
This paper presents research regarding the influence of turbulent kinetic energy (TKE) level on accuracy of Reynolds averaged Navier–Stokes (RANS) based turbulence models.
