Development Of A TwoFluid Drag Law For Clustered Particles Using Direct Numerical Simulation And Validation Through Experiments, Ahmadreza Abbasi Baharanchi
FIU Electronic Theses and Dissertations
This dissertation focused on development and utilization of numerical and experimental approaches to improve the CFD modeling of fluidization flow of cohesive micron size particles. The specific objectives of this research were: (1) Developing a cluster prediction mechanism applicable to TwoFluid Modeling (TFM) of gassolid systems (2) Developing more accurate drag models for TwoFluid Modeling (TFM) of gassolid fluidization flow with the presence of cohesive interparticle forces (3) using the developed model to explore the improvement of accuracy of TFM in simulation of fluidization flow of cohesive powders (4) Understanding the causes and influential factor which led to improvements and ...

Pattern Formation Of Elastic Waves And Energy Localization Due To Elastic Gratings, A. Berezovski, J. Engelbrecht, Mihhail Berezovski
Publications
Elastic wave propagation through diffraction gratings is studied numerically in the plane strain setting. The interaction of the waves with periodically ordered elastic inclusions leads to a selfimaging Talbot effect for the wavelength equal or close to the grating size. The energy localization is observed at the vicinity of inclusions in the case of elastic gratings. Such a localization is absent in the case of rigid gratings.

Mechanical & Aerospace Engineering Faculty Publications
An energy harvesting concept has been proposed comprising a piezoelectric patch on a vertical cantilever beam with a tip mass. The cantilever beam is excited in the transverse direction at its base. This device is highly nonlinear with two potential wells for large tip masses, when the beam is buckled. For the prebuckled case considered here, the stiffness is low and hence the displacement response is large, leading to multiple solutions to harmonic excitation that are exploited in the harvesting device. To maximise the energy harvested in systems with multiple solutions the higher amplitude response should be preferred. This paper ...

Almost Sure Asymptotic Stabilization Of Differential Equations With TimeVarying Delay By Lévy Noise, Dezhi Liu, Weiqun Wang, Jose Luis Menaldi
Almost Sure Asymptotic Stabilization Of Differential Equations With TimeVarying Delay By Lévy Noise, Dezhi Liu, Weiqun Wang, Jose Luis Menaldi
Mathematics Faculty Research Publications
This paper aims to determine that the Lévy noise can stabilize the given differential equations with timevarying delay, which has generalized the Brownian motion case. An analysis is developed and sufficient conditions on the stabilization for stochastic differential equations with timevarying delay are presented. Our stabilization criteria is in terms of linear matrix inequalities (LMIs), whence the feedback controls can be designed more easily in practice.
Step Growth And Meandering In A PrecursorMediated Epitaxy With Anisotropic Attachment Kinetics And Terrace Diffusion, Mikhail Khenner
Step Growth And Meandering In A PrecursorMediated Epitaxy With Anisotropic Attachment Kinetics And Terrace Diffusion, Mikhail Khenner
Mikhail Khenner
Step meandering instability in a BurtonCabreraFrank (BCF)type model for the growth of an isolated, atomically high step on a crystal surface is analyzed. It is assumed that the growth is sustained by the molecular precursors deposition on a terrace and their decomposition into atomic constituents; both processes are explicitly modeled. A strongly nonlinear evolution PDE for the shape of the step is derived in the longwave limit and without assuming smallness of the amplitude; this equation may be transformed into a convective CahnHilliardtype PDE for the step slope. Meandering is studied as a function of the precursors diffusivity and ...
ElectromigrationDriven Evolution Of The Surface Morphology And Composition For A BiComponent Solid Film, Mikhail Khenner, Mahdi Bandegi
ElectromigrationDriven Evolution Of The Surface Morphology And Composition For A BiComponent Solid Film, Mikhail Khenner, Mahdi Bandegi
Mikhail Khenner
A two PDEsbased model is developed for studies of a morphological and compositional evolution of a thermodynamically stable alloy surface in a strong electric field, assuming different and anisotropic diffusional mobilities of the two atomic components. The linear stability analysis of a planar surface and the computations of morphology coarsening are performed. It is shown that the conditions for instability and the characteristic wavelength and growth rate differ from their counterparts in a singlecomponent film. Computational parametric analyses reveal the sensitivity of the scaling exponents to the electric field strength and to the magnitude of anisotropies difference.
