The Sun is our nearest star; it is also the most important star that determines life on Earth. A
large variety of phenomena observed on the Sun's surface, with potential impact on Earth, is …

Natural convection arising over vertical and horizontal heated flat surfaces is one of the most
ubiquitous flows at a range of spatiotemporal scales. Despite significant developments over …

Wall-bounded turbulent flows can take different statistically stationary turbulent states, with
different transport properties, even for the very same values of the control parameters. What …

We numerically study the melting process of a solid layer heated from below such that a
liquid melt layer develops underneath. The objective is to quantitatively describe and …

Thermally driven turbulent flows are omnipresent in nature and technology. A good
understanding of the physical principles governing such flows is key for numerous problems …

In turbulent Rayleigh–Bénard (RB) convection with regular, mono-scale, surface roughness,
the scaling exponent, when the smaller roughness elements fully protrude through the …

The heat transfer scaling theories for Rayleigh‐Bénard convection (RBC) are reviewed and
discussed for configurations with and without rotation and magnetic fields. Scaling laws are …

Rayleigh–Bénard (RB) convection with free-slip plates and horizontally periodic boundary
conditions is investigated using direct numerical simulations. Two configurations are …

With the aim of efficiently simulating three-dimensional multiphase turbulent flows with a
phase-field method, we propose a new discretization scheme for the biharmonic term (the …

High–Rayleigh number convective turbulence is ubiquitous in many natural phenomena
and in industries, such as atmospheric circulations, oceanic flows, flows in the fluid core of …
