Polar regions are covered by sea ice, which can be seen as a thin solid elastic sheet with heterogeneous mechanical properties. The dynamics of deformation of a floating solid sheet is primarily governed by gravity, water density, and the flexural modulus, which depends on its mechanical properties,…

Binary droplet collisions exhibit four primary outcomes at Weber number (We) below 100, i.e., bouncing, coalescence, reflexive separation, and stretching separation. At We exceeding 300, shattering becomes prominent, characterized by the catastrophic disintegration of the merged mass and ejection of…

Here, we propose a valveless nanopump model, featuring a two-dimensional graphene slit that can only accommodate a single layer of water molecules. Using molecular dynamics simulations, we demonstrate the feasibility of inducing water transport via mechanical vibrations at the slit entrance, even in…

We obtain the equations of fluctuating hydrodynamics for many-particle systems whose microscopic units have both translational and rotational motion. The orientational dynamics of each element are studied in terms of Langevin equations for the rotational motion of a corresponding fixed-length direct…

Ternary systems driven by concentration-dependent diffusion coefficients were studied aboard the International Space Station. A range of new patterning possibilities and the coexistence of gravitational instabilities, previously thought impossible in nonreactive systems, were uncovered.

Direct numerical simulation is utilized to resolve the drag and turbulent characteristics of supersonic fully developed channel turbulence in this paper. Distinct from spatially developing turbulence, a relaxation of the skin friction coefficient is discovered after blowing in fully developed turbul…

This study investigates the influence of varying degrees of freedom (DOFs) on the swimming performance of self-propelled undulatory swimmers navigating a straight path in three flow configurations: an unbounded fluid, near a solid wall, and in a side-by-side arrangement. Vertical and rotational DOFs…

A rigorous formalism is presented for the time-averaged acoustic radiation force on a spherical particle near an infinite planar boundary subjected to a plane wave. The background medium is assumed to be a weakly thermoviscous fluid, with the viscous and thermal boundary layers much smaller than eit…

In this work, an improved Allen-Cahn-based phase-field lattice Boltzmann model is presented which is applicable to heat transfer in two-phase flow involving evaporation. The vapor concentration at the liquid-vapor interface serves as the driving force for vaporization. In our improved model, four di…

The process of producing a liquid column is common in daily life and industrial applications, such as walking through a puddle and roller printing. While governed by the Navier-Stokes equation, its dynamics are often studied by numerical means, which hinders a full understanding of the rich mixture …

This study develops a weighted-residual model for Oldroyd-B films on slippery substrates at moderate Reynolds number and large slippery length. Linear stability analysis reveals that wall slip promotes perturbation growth rates, increases cut-off wave numbers, and accelerates long-wave propagation s…
