Long-Pulsed Laser-Induced Cavitation: Laser-Fluid Coupling, Phase Transition, and Bubble Dynamics
… the dynamics and thermodynamics of a two-phase fluid flow. In this new method, the model combines the Navier-Stokes (NS) equations for a compressible inviscid two-phase fluid flow, a new laser radiation equation, and a novel local thermodynamic model of phase transition. The Navier-Stokes …

Direct numerical simulations of multiphase flow with applications to basaltic volcanism and planetary evolution
… into two parts. The first part investigates gas-fluid coupling during the buoyant ascent of an exsolved gas phase in the conduit of basaltic volcanoes. The second part examines the solidification processes in magma oceans which entail both degassing (gas-fluid coupling) and crystallization …

A conformable ultrasound patch for cavitation enhanced transdermal cosmeceutical delivery
… intermediate-frequency sonophoresis in the fluid coupling medium between the patch and the skin. The cUSP consists of piezoelectric transducers embedded in a soft elastomer to create localized cavitation pockets (0.8 cm², 1 mm deep) over larger areas of conformal contact (20 cm²). …

Modeling of mechanical energy dissipation of low-dimensional resonators
… or phonons and extrinsic dissipation due to a fluid environment. In this context, low-dimensional resonators need special attention because the dissipation cannot be explained using the existing continuum theories. Due to atomic thickness, sub-micron dimension, and mega- to gigahertz …

Transport modeling of simple fluids and nano-colloids : thermal conduction mechanisms and coarse projection
… conductivity with volume fraction and solid-fluid interaction is examined. For a specific system of nanosized platinum clusters which interact strongly with host liquid xenon, a significant thermal conductivity enhancement is obtained as a result of self correlation in the potential energy …

Conformable Ultrasound Face Patch for Cavitation-enhanced Transdermal Cosmeceutical Delivery
… full two-dimensional array. Localized pockets of fluid coupling medium are created between the cUFP and skin. This approach provides sufficient reservoir space for inertial cavitation, convective mixing, and microjet formation with the application of ultrasound. Multiphysics simulation models are …

The Correlated Dynamics of Micron-Scale Cantilevers in a Viscous Fluid
… include a variety of configurations and viscous fluids. It is first shown that the correlated dynamics of both a laterally and vertically offset cantilever pair can be accurately predicted by numerical simulations. This is verified by comparing the correlated dynamics yielded by numerical …

The Stochastic Dynamics of an Array of Micron Scale Cantilevers in Viscous Fluid
… spaced micron scale cantilevers in a viscous fluid is considered. The stochastic cantilever dynamics are due to the constant buffeting of fluid particles by Brownian motion and the dynamics of adjacent cantilevers are correlated due to long range effects of fluid dynamics. The measurement …

Effect of grazing flow on structural-acoustic response of an elastic plate with sound in a duct
… damping of the plate, and the plate modal coupling through the duct acoustic field. The theory is extended to estimate the onset of instability in the structural response of a duct-mounted clamped-plate with grazing flow for estimating its range of applicability. Numerical simulations of …

Three-dimensional multi-scale hydraulic fracturing simulation in heterogeneous material using Dual Lattice Model
… is proposed for hydraulic fracture simulation by coupling a solid lattice model with a fluid lattice model. From DLM simulations of hydraulic fracturing of the classical penny shape crack problem under hydrostatic condition, the heterogeneities from both the fracture asperity and the applied …

Simulations of subsurface multiphase flow including polymer flooding in oil reservoirs and infiltration in vadose zone
… chemistry has a strong effect on reaction and fluid rheology, which in turn has a strong effect on fluid transport. We have implemented a well-established polymer model within the Implicit Parallel Accurate Reservoir Simulator (IPARS), which enables parallel simulation of non-Newtonian fluid …
