Precipitation is still one of the most complex climate variables to observe, to understand, and to handle within climate monitoring and climate analysis as well as to simulate in numerical weather prediction and climate models. Especially over ocean,

As a renewable fuel, hydrogen (H2) may play an increasingly important role in the development and control of piston and gas turbine engines to achieve zero carbon emissions. Predictive modeling of H2-fueled combustion processes requires a clear under

Recent studies have shown that Soret diffusion (SD), driven by temperature gradients, could play an important role in both laminar and turbulent premixed H2 flames. However, comparatively little effort has been made to investigate SD effects on turbu

Flamelet-based combustion models have been extensively used in the modeling of turbulent non-premixed combustion due to their notable advantages in reducing computational cost. The classical one-dimensional flamelet equations are derived based on an

It is well understood how the flame structure of laminar non-premixed counterflow flames is influenced by differential diffusion, which is driven by species gradients, and corresponding models are available for physical and flamelet space. Thermal di

Scale-resolving simulations (SRS) are becoming more and more important for internal combustion (IC) engine simulations and are gradually replacing first-generation unsteady Reynolds-averaged Navier-Stokes (URANS) based approaches. In addition to the

Based on in-situ tracking of gradient trajectories in a direct numerical simulation (DNS), this work combines a structural analysis of a turbulent, temporally evolving syngas jet with an extended flamelet model. This flamelet formulation accounts for

Most reacting and two-phase flows of practical interest are turbulent but take place at low Mach numbers or under incompressible conditions. In order to investigate the properties of such complex flows with high accuracy but acceptable computing time

Direct numerical simulation data of a jet with two passive scalars is compared to explicitly filtered data of the same case with regard to the influence of the turbulent/nonturbulent interface (TNTI) on differential diffusion. Filtering is found to a

The early development of severe convective storms over central Europe was investigated on the basis of nine cases from 2012. Using data from the Spinning Enhanced Visible and Infrared Imager (SEVIRI) imaging radiometer aboard a geostationary Meteosat
