Flow field data of three-dimensional Riemann problems [PDF]

Data in Brief
Common validation and verification test cases for compressible flow solvers are only one- or two-dimensional. Such flows, however, are inherently three-dimensional.

A direct-hybrid CFD/CAA method based on lattice Boltzmann and acoustic perturbation equations

Acta Acustica, 2023
The accuracy of two direct coupled two-step CFD/CAA methods is discussed. For the flow field either a finite-volume (FV) method for the solution of the Navier–Stokes equations or a lattice Boltzmann (LB) method is coupled to a discontinuous Galerkin (DG)

Drop Impact onto a Substrate Wetted by Another Liquid: Flow in the Wall Film

Colloids and Interfaces, 2022
The impact of a drop onto a liquid film is relevant for many natural phenomena and industrial applications such as spray painting, inkjet printing, agricultural sprays, or spray cooling.

Thermosuperrepellency of a hot substrate caused by vapour percolation

Communications Physics, 2021
Droplet impact on surfaces has wide applications regardless of the discipline area and several hypotheses have been put forward to explain the mechanism of film boiling.

Inferring incompressible two-phase flow fields from the interface motion using physics-informed neural networks

Machine Learning with Applications, 2021
In this work, physics-informed neural networks are applied to incompressible two-phase flow problems. We investigate the forward problem, where the governing equations are solved from initial and boundary conditions, as well as the inverse problem, where

Aerodynamics [PDF]

, 2021
Aerodynamics, the study of air motion around solid objects, allows us to understand and measure the dominating forces acting on aircrafts, buildings, bridges, automobiles, and other structures. The forces that result in an aircraft overcoming gravity and

An experimental study of regime transitions in a differentially heated baroclinic annulus with flat and sloping bottom topographies [PDF]

Nonlinear Processes in Geophysics, 2014
A series of laboratory experiments has been carried out in a thermally driven rotating annulus to study the onset of baroclinic instability, using horizontal and uniformly sloping bottom topographies.
