Abstract

Purpose

The Lattice Boltzmann (LB) method offers an alternative to conventional computational fluid dynamics (CFD) methods. However, its practical use for complex turbulent flows of engineering interest is still at an early stage. This paper aims to outline an LB wall-modeled large-eddy simulation (WMLES) solver.

Design/methodology/approach

The solver is dedicated to complex high-Reynolds flows in the context of WMLES. It relies on an improved LB scheme and can handle complex geometries on multi-resolution block structured grids.

Findings

Dynamic and acoustic characteristics of a turbulent airflow past a rod-airfoil tandem are examined to test the capabilities of this solver. Detailed direct comparisons are made with both experimental and numerical reference data.

Originality/value

This study allows assessing the potential of an LB approach for industrial CFD applications.

Abstract

An account of two cases of alleged sale of adulterated butter was published in the Oldham Evening Chronicle of the 25th April last, and in the Oldham Standard of the 26th of the same month. The facts as reported call for comment, not because they are in any way extraordinary—they are indeed essentially common place—but the method of dealing with them by the Oldham Health Committee seems to us to be so.
