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,…
Buoyancy-driven attraction of active droplets
Yibo Chen, Kai Leong Chong, Haoran Liu +2
Active oil droplets in a liquid are believed to repel due to the Marangoni effect, while buoyancy effects caused by the density difference between the droplets, diffusing product,…
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 hea…
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…
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…
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…
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…
