Heat transfer in turbulent Rayleigh-Bénard convection within two immiscible fluid layers
Hao-Ran Liu, Kai Leong Chong, Rui Yang +2
We numerically investigate turbulent Rayleigh-Bénard convection within two immiscible fluid layers, aiming to understand how the layer thickness and fluid properties affect the he…
Two-layer Thermally Driven Turbulence: Mechanisms for Interface Breakup
Hao-Ran Liu, Kai Leong Chong, Qi Wang +3
It is commonly accepted that the breakup criteria of drops or bubbles in turbulence is governed by surface tension and inertia. However, also {\it{buoyancy}} can play an important…
Visibility graph analysis of the grains and oilseeds indices
Hao-Ran Liu, Ming-Xia Li, Wei-Xing Zhou
The Grains and Oilseeds Index (GOI) and its sub-indices of wheat, maize, soyabeans, rice, and barley are daily price indexes reflect the price changes of the global spot markets of…
Ice melting in salty water: layering and non-monotonic dependence on the mean salinity
Rui Yang, Christopher J. Howland, Hao-Ran Liu +2
The presence of salt in ocean water strongly affects the melt rate and the shape evolution of ice, both of utmost relevance in geophysical and ocean flow and thus for the climate.…
Regime transitions in thermally driven high-Rayleigh number vertical convection
Qi Wang, Hao-Ran Liu, Roberto Verzicco +2
Vertical convection is investigated using direct numerical simulations over a wide range of Rayleigh numbers with fixed Prandtl number , in a two-dime…
An efficient phase-field method for turbulent multiphase flows
Hao-Ran Liu, Chong Shen Ng, Kai Leong Chong +2
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 4…
Bistability in radiatively heated melt ponds
Rui Yang, Christopher J. Howland, Hao-Ran Liu +2
Melting and solidification processes, intertwined with convective flows, play a fundamental role in geophysical contexts. One of these processes is the formation of melt ponds on g…
Improved phase field model for two-phase incompressible flows: Sharp interface limit, universal mobility and surface tension calculation
Jing-Wei Chen, Chun-Yu Zhang, Hao-Ran Liu +1
In this paper, we propose an improved phase field model for interface capturing in simulating two-phase incompressible flows. The model incorporates a second-order diffusion term,…
Precise determination of Pb Decay Spectrum at 0 keV and its Implication to Theoretical Calculations
Shuo Zhang, Xavier Mougeot, Hao-Ran Liu +12
The atomic exchange effect will lead to a significant increase in the probability density of decays below a few keV. This effect is very important for scientific experiments t…
Turbulent Rayleigh-Bénard convection with bubbles attached to the plate
Hao-Ran Liu, Kai Leong Chong, Rui Yang +2
We numerically investigate turbulent Rayleigh-Bénard convection with gas bubbles attached to the hot plate, mimicking a core feature in electrolysis, catalysis, or boiling. The ex…
Enhancing Heat Transport in Multiphase Rayleigh-Bénard Turbulence by Changing the Plate-Liquid Contact Angles
Hao-Ran Liu, Kai Leong Chong, Chong Shen Ng +2
This numerical study presents a simple but extremely effective way to considerably enhance heat transport in turbulent multiphase flows, namely by using oleophilic walls. As a mode…
Transition edge sensor based detector: from X-ray to -ray
