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 …

Composite separation membranes are essential in the fields of water treatment, mass
concentration, purification, solvent exchange, gas separation, energy storage and …

With the growing global warming and energy issues, gas separation like carbon capture and
hydrogen purification are becoming increasingly important. Membrane separation …

Turbulent Rayleigh-Bénard convection displays a large-scale order in the form of rolls and
cells on lengths larger than the layer height once the fluctuations of temperature and velocity …

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 …

We report the observation of superstructures, ie, very large-scale and long living coherent
structures in highly turbulent Rayleigh-Bénard convection up to Rayleigh Ra= 10 9. We …

The large-scale circulation (LSC) of fluid is one of the main concepts in turbulent thermal
convection as it is known to be important in global heat and mass transport in the system. In …

Statistical properties of turbulent Rayleigh–Bénard convection at low Prandtl numbers, but
the scaling exponent of its growth with Rayleigh number is reduced. Our analysis of the …
