This paper introduces physics-informed Transformer operators (PITO and PIITO) that leverage the Vision Transformer architecture and embedded LES equations to accurately and efficiently predict 3D turbulence with superior stability, lower memory usage, and fewer parameters compared to existing methods like PIFNO, all without requiring labeled training data.
This study employs axisymmetric numerical simulations to investigate how impact velocity, fluid properties, and drop shape influence the coalescence dynamics of a liquid drop in a deep pool, revealing that prolate drops most readily form secondary droplets, that Rayleigh-Plateau instability is insignificant in this context, and that a transition regime with multiple neck oscillations exists between partial and complete coalescence.
This study demonstrates that seal whisker-inspired geometries enhance wake-induced vibration sensitivity by exhibiting lower fluid damping and greater amplitude response compared to elliptical cylinders, a behavior accurately captured by an amplitude-dependent Van der Pol damping model.
This paper extends the k-omega0 turbulence model to account for surface roughness by introducing an effective origin that links log-layer offsets to equivalent sandgrain roughness, while deriving a virtual origin formula that ensures consistency with the fully rough flow limit.
This paper presents a mathematically consistent reduced-order model coupling Kirchhoff-Love plate bending with Reynolds lubrication theory, implemented via a monolithic interior-penalty finite element scheme in FEniCSx, to simulate and analyze the nonlinear fluid-structure interaction dynamics of wafer-to-wafer bonding.
This paper proposes and validates a reduction-consistent diffuse-interface model coupled with a lattice Boltzmann method to accurately and efficiently simulate N-phase flows involving liquid-solid phase change, including complex interactions with insoluble impurities.
This study utilizes direct numerical simulation of a three-stream mixing layer to demonstrate that MILD combustion, characterized by high dilution, is primarily driven by mixing with hot products leading to a premixed-autoignition mode, whereas non-MILD conditions rely more on fuel-air mixing and premixed-deflagrative combustion.
This paper utilizes validated smoothed particle hydrodynamics simulations to investigate the coefficient of restitution in wet collisions within a moderate-to-high Weber number regime, revealing a scaling law dependent on the Stokes number and dimensionless film thickness that exhibits two distinct power-law regimes.
This paper proposes and demonstrates a single-cell deposition method using the electrospray cone-jet mode near its minimum-flow-rate stability limit, which enables high spatial resolution placement of individual cells while maintaining their viability.
This study proposes and validates through a mathematical stability analysis and experimental data that dryout inception in two-phase CO2 annular flow within microchannels is triggered by liquid-vapour interface instability, identifying a critical vapour quality threshold () that governs this phenomenon.
