We present an overview of the aerodynamics of heavy vehicles, such as tractor-trailers, high-
speed trains, and buses. We introduce three-dimensional flow structures around simplified …

A fully connected neural network (NN) is used to develop a subgrid-scale (SGS) model
map** the relation between the SGS stresses and filtered flow variables in a turbulent …

An eddy-viscosity based, subgrid-scale model for large eddy simulations is derived from the
analysis of the singular values of the resolved velocity gradient tensor. The proposed σ …

A neural-network-based large eddy simulation is performed for flow over a circular cylinder.
To predict the subgrid-scale (SGS) stresses, we train two fully connected neural network …

Spectral energy transfer in a turbulent channel flow is investigated at Reynolds number,
based on the wall shear velocity and channel half-height, with a particular emphasis on full …

This paper focusses on three main numerical methods, ie, the Reynolds-Averaged Navier-
Stokes (RANS), Large Eddy Simulation (LES), and Direct Numerical Simulation (DNS) …

The main idea of this manuscript is to assess the wall-adapting local eddy-viscosity (WALE)
model, which is designed for large-eddy simulation (LES) of turbulent boundary layer, in …

Direct simulations of the incompressible Navier-Stokes equations are limited to relatively low-
Reynolds numbers. Hence, dynamically less complex mathematical formulations are …

The flow characteristics in a volute-type centrifugal pump operating at design (Q d= 35 m
3/h) and off-design (Q off= 20 m 3/h) conditions are investigated using large eddy simulation …

Abstract Large Eddy Simulations (LES) were carried out on a centrifugal pump in order to
investigate the effect on pressure fluctuations through rotating and stationary channels by …
