Fluid-dynamic assessment of sugarcane bagasse to use as feedstock in bubbling fluidized bed gasifiers
(Elsevier B.V., 2014-12-05)
The fluid bed gasification of a sugarcane bagasse is a promising option for the large-scale production of fuel gas in order to increase the energetic efficiency of the sugar industry. A fluid-dynamic and thermodynamic ...
Coarsening dynamics of the one-dimensional Cahn-Hilliard model
(2005)
The dynamics of one-dimensional Cahn-Hilliard model is studied. The stationary and particle-type solutions,
the bubbles, are perused as a function of initial conditions, boundary conditions, and system size. We characterize
the ...
Scaling laws in the dynamics of collapse of single bubbles and 2D foams
(American Chemical Society, 2020-12-07)
Avalanches of rupturing bubbles play an important role in the dynamics of collapse of macroscopic liquid foams. We hypothesized that the occurrence of cascades of rupturing bubbles in foams depends, at least in part, on ...
A comparative assessment of empirical and lattice Boltzmann method-based drag models for simulation of gas–solid flow hydrodynamics in a bubbling fluidized bed
(2017-08-01)
In simulations of fluidized beds using computational fluid dynamics (CFD), the description of gas–solid flow hydrodynamics relies on a drag model to account for the momentum transfer between gas and solid phases. Although ...
Drift Velocity Estimation of Ionospheric Bubbles Using GNSS Observations
(2021-08-01)
Equatorial plasma bubble (EPB) irregularities are large-scale plasma depleted structures that exist in the equatorial and low-latitude ionosphere. Thus, particularly in these regions, much attention must be given to the ...
A novel water hammer device designed to produce controlled bubble collapses
(Elsevier Inc., 2018-04)
In this work, a novel prototype of a water hammer device designed to produce controlled collapses of a single cavitation bubble is presented. It employs a new driving method in which a laser generated bubble is initially ...
