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 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 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.
This study relaxes the symmetric neutrality assumption in tropical cyclone potential intensity theory to derive a generalized formula that accurately quantifies the dynamical and thermodynamic constraints on vortex structure and maximum wind speed under non-symmetric conditions, revealing that the saturation entropy gradient at constant temperature governs balanced intensity and that the symmetric neutrality assumption is invalid during rapid intensification.
This paper presents the development and validation of two new OpenFOAM solvers, epotMicropolarFoam and epotMMRFoam, which simulate magnetohydrodynamic micropolar flows and demonstrate that incorporating micromagnetorotation significantly reduces fluid velocity and microrotation while suppressing vortex cores, offering critical insights for biomedical applications like targeted drug delivery.
This paper derives a thermodynamically consistent free boundary model for two-phase flows in an evolving domain that incorporates bulk-surface interactions via convective Cahn--Hilliard equations and generalized Navier slip conditions, unifying previous models through rigorous derivation via Lagrange Multiplier and Energetic Variational approaches.
This paper proposes a data-driven approach to analyze transient growth in shear flows by directly optimizing energy growth from input-output data pairs, thereby eliminating the need for explicit linearization or complex coding while successfully validating the method against noise-corrupted models and applying it to experimental boundary layer data.
This paper employs PDE-constrained optimization to identify specific initial conditions for the 1D viscous Burgers equation that evolve into self-similar energy cascades consistent with Kolmogorov's theory, distinguishing between decaying viscous and growing inertial solution families that rely on wave front steepening at low viscosities.
This study presents the first direct, time-resolved three-dimensional measurements of the flow field generated by a free-swimming *Chlamydomonas reinhardtii* alga, revealing complex vortex dynamics and topological changes that refine our understanding of microbial locomotion, feeding efficiency, and energy expenditure.
