Computational Analysis of Gas Transport in Fuel Cell Catalyst Layer under Dry and Partially Saturated ConditionsDownload
A computational study is performed to analyze oxygen transport in dry and wet stochastically reconstructed catalyst layers (CLs). CL stochastic reconstructions are generated using random penetrating spheres of a given particle size that agree with the statistical correlation functions of a...
We present a linear theory of lipid membranes which accommodates the effects of intra-membrane viscosity into the model of deformations. Within the Monge parameterization, a linearized version of the shape equation describing membrane morphology is derived. Admissible boundary conditions are...
The dynamics of a fully nonlinear, tree-structured resonator and its response to a broadband forcing of the branches is examined. It is shown that the broadband forcing yields a transfer of energy between the parts of the spectrum so that the spectrum becomes progressively more narrow-band for...
We report upon a theoretical and experimental investigation of a porous medium ‘filling box’ flow by specifically examining the details of the laminar descending plume and its outflow in a control volume having an impermeable bottom boundary and sidewalls. The plume outflow initially comprises a...
The traditional approach of cooling tower plume abatement is supposed to result in an unsaturated, well-mixed plume with a ‘‘top-hat” structure in the radial structure, but this is an idealization that is rarely achieved in practice. Meanwhile, previous analyses have shown that there may be an...
The application of turbulent plume theory in describing the dynamics of emptying filling boxes, control volumes connected to an infinite exterior through a series of openings along the upper and lower boundaries, has yielded novel strategies for the natural ventilation of buildings. Making the...
Buoyancy-driven exchange flow between two adjacent building zones connected with top and bottom ventsDownload
We examine the buoyancy driven flow between two adjacent building zones separated by top and bottom vents with and without a source of buoyancy. In the absence of a source, by opening the vents, the pressure difference between the two zones drives the exchange flow. When there is an isolated...
Most recent research on flywheel rotors has focused on high-speed composite rotors as the storage element of the flywheel energy storage system (FESS). Literature research indicates that this is primarily due to the high specific energy of composites compared to metals. However, a quantitative...
We examine the transient evolution of a negatively buoyant, laminar plume in an emptying filling box containing a uniform porous medium. In the long time limit, the box is partitioned into two uniform layers of different densities. However, the approach towards steady state is characterized by a...
