Thermochromic hydrogels exhibit a smart capacity for regulating solar spectrum transmission, enabling automatically change their transmissivity in response to the ambient temperature change. This has great importance energy conservation purposes. Military and civilian emergency thermochromic applications require rapid visible-light stealth (VLS); however, concurrent transmission VLS is yet be realized. Inspired by squid-skin, we propose micropatterned hydrogel (MTH) realize control of...
In this paper, we developed a unified lattice Boltzmann model (LBM) to simulate electroconvection in dielectric liquid induced by unipolar charge injection. Instead of solving the complex set coupled Navier-Stokes equations, conservation equation, and Poisson equation electric potential, three consistent equations are formulated. Numerical results presented for both strong weak injection regimes, different scenarios onset evolution instability, bifurcation, chaos tracked. All LBM found be...
Charge injection induced electroconvection in a dielectric liquid lying between two parallel plates is numerically simulated three dimensions (3D) using unified lattice Boltzmann method (LBM). Cellular flow patterns and their subcritical bifurcation phenomena of 3D are investigated for the first time. A unit conversion also derived to connect LBM system real physical system. The codes validated by carefully chosen cases all results found be highly consistent with analytical solutions or...
Metasurfaces, the two-dimensional (2D) counterpart of metamaterials, have recently attracted a great deal attention due to their amazing properties, including negative refraction, hyperbolic dispersion, and manipulation evanescent spectrum. In this work, theory model is proposed for near field radiative heat transfer (NFRHT) between two nanoparticles in presence an anisotropic metasurface. Specifically, metasurface modeled as array graphene strips (GS), which ideal platform implement any...
In this paper, a numerical investigation of bubble dynamics during nucleate pool boiling is conducted using the lattice Boltzmann method (LBM). Unlike perfectly dielectric fluid assumption used in most previous studies, leaky-dielectric model (LDM) work allows free charges to accumulate at gas-liquid interface and more closely models real physical situation. The fully coupled equations are solved by combining pseudopotential LBM with phase-change LDM. validated four fundamental cases results...
Electrohydrodynamic pumps, as a representative type of nonmechanical pump, have received significant research attention due to their inherent advantages having no moving parts and low power consumption. In particular, the planar charge injection pump has exhibited superior fluid driving performance, making it highly promising for applications in microscale flow chip cooling. A sandwich structure with multiple pairs interdigitated electrodes is numerically studied this paper. The interaction...
Melting in the presence of electrohydrodynamic (EHD) flow driven by Coulomb force dielectric phase change material is numerically studied. A model developed for EHD solid-liquid process. The fully coupled equations including mechanical equations, electrical energy and continuity interface are solved using a unified lattice Boltzmann (LBM). Firstly, numerical validated several cases hydrostatic state, all LBM results found to be highly consistent with analytical solutions. Besides, our code...
A thermal diode based on the asymmetric radiative heat transfer between nanoparticles assisted by nonreciprocal graphene plasmons waveguides is proposed in this work. The system consists of two particles and a drift-biased suspended sheet close proximity them. Nonreciprocal are induced drift currents sheet, then couple to waves emitted near-field regime. Based asymmetry with respect their propagation direction plasmons, rectification observed. performance can be actively adjusted through...
Near-field radiative heat transfer exhibits various effects, such as amplification due to the geometry of system. In this work, we construct a periodic layered structure which consists multiple layers alternating materials. Radiative (RHT) between nanoparticles placed on each side an intermediate is studied. Thermal energy exchange assisted by transmitted evanescent fields, theoretically included in system's Green's function. We show that resulting with assistance multilayered more than five...
A complete lattice Boltzmann model (LBM) is proposed for the steady radiative transfer equation (RTE). The RTE can be regarded as a pure convection with source term. To derive expressions equilibrium distribution function and relaxation time, an artificial isotropic diffusion term introduced to form convection-diffusion equation. When dimensionless time has value of 0.5, (LBE) exactly applicable original RTE. We also perform multiscale analysis based on Chapman-Enskog expansion recover...
