This study demonstrates that Denoising Diffusion Probabilistic Models (DDPMs) and their latent-space variants (LDMs) provide high-accuracy, computationally efficient frameworks for predicting complex physical fields, including thermal distributions and flow regimes ranging from incompressible to hypersonic.
This paper establishes the local-in-time existence of strong solutions to the gravity water wave kinetic equation by rigorously deriving a sharper bound for the collision kernel's growth in the highly non-local regime and utilizing this improved estimate to overcome the associated singular integral challenges.
This paper reviews analytical methods for solving low-Reynolds-number wedge and corner flow problems using the Papkovich-Neuber representation and the Fourier-Kontorovich-Lebedev integral transform to characterize Stokeslet and rotlet solutions for applications in microfluidics and confined hydrodynamics.
This paper introduces "Pufflets" as inertial counterparts to Stokeslets to demonstrate that metachronal waves of cilia can drive highly efficient particle transport through inertial coasting, a mechanism impossible in low-Reynolds-number Stokes flow.
This study utilizes Surface Evolver simulations to define the geometric and capillary pressure conditions under which "bridging" enables stable, simultaneous two-phase flow in microfluidic porous media, demonstrating that such steady flow is achievable in networks with cylindrical pillars but not in long, curved channels where snap-off dominates.
This paper presents a dark fluid model described as a non-viscous, non-relativistic, rotating, and self-gravitating fluid with spherical symmetry and a polytropic equation of state, which is solved using a self-similar time-dependent ansatz to derive new solutions consistent with the Newtonian cosmological framework that can describe the transition from normal matter to dark energy on cosmological scales.
This paper proposes a consistent multiple-relaxation-time lattice Boltzmann method that decouples void fraction from density and employs a penalty source term to eliminate spurious velocities, thereby accurately recovering the volume-averaged Navier-Stokes equations with second-order accuracy for complex fluid-solid multiphase flows.
This paper investigates the impact of transverse strain on turbulent mixing layers across linear, transitional, and self-similar regimes, revealing that while transverse compression amplifies instability growth in the linear regime, it paradoxically suppresses growth in the transitional-to-turbulent regime by altering shear production and turbulent kinetic energy distribution, ultimately allowing for width prediction via an adjusted buoyancy-drag model.
This paper presents a thermodynamically admissible, improved diffuse interface model for nanoscale dense fluid transport that enhances the conventional Navier-Stokes-Korteweg formulation by incorporating density-gradient-dependent viscosity and thermal conductivity, thereby accurately capturing interfacial resistance and transport phenomena in non-equilibrium liquid-vapor systems.
Motivated by varicose vein sclerotherapy, this study analyzes pressure-driven Bingham fluid flows in curved channels with Navier slip, revealing that while wall slip reduces stagnant foam regions in high-curvature areas, it also narrows the unyielded plug, potentially compromising the foam's efficacy in displacing blood.
