Sound Generation by a Turbulent Flow in Musical Instruments - Multiphysics Simulation Approach - [PDF]
, 1998 Total computational costs of scientific simulations are analyzed between direct numerical simulations (DNS) and multiphysics simulations (MPS) for sound generation in musical instruments. In order to produce acoustic sound by a turbulent flow in a simple

Statistical Uncertainty of DNS in Geometries without Homogeneous Directions
Applied Sciences, 2021 In this paper, we present uncertainties of statistical quantities of direct numerical simulations (DNS) with small numerical errors. The uncertainties are analysed for channel flow and a flow separation case in a confined backward facing step (BFS ...

Single-Mode Solutions for Convection and Double-Diffusive Convection in Porous Media
Fluids, 2022 This work employs single-mode equations to study convection and double-diffusive convection in a porous medium where the Darcy law provides large-scale damping. We first consider thermal convection with salinity as a passive scalar.

Numerical analysis of a fully developed non-isothermal particle-laden turbulent channel flow
Archives of Mechanics, 2011 Turbulent non-isothermal fully-developed channel flow laden with small particles was investigated through Direct Numerical Simulation (DNS), combined with tracking of the individual particles. The simulations are performed at Reτ=180 and 395, with Pr = 1.

The Barrel of Ilmenau: A large-scale convection experiment to study dust devil-like flow structures.
Meteorologische Zeitschrift, 2021 We present an experimental facility for the validation of numerical simulations on atmospheric dust devils in a controlled laboratory experiment. Dust devils are atmospheric air vortices with a vertical axis, and are formed by intense solar radiation and
