Macromolecular Reaction Engineering, Volume 16, Issue 6, December 2022., 2022 Two different approaches are used to simulate the fluidization behavior of Geldart A–B particles in fluidized bed reactors operated in the bubbling regime. 2D computational fluid dynamics Euler‐Euler predictions are compared to results of a compartment‐based model with simplified fluid‐dynamics description. The compartmentalized approach is appropriate

Advanced Theory and Simulations, EarlyView.Increasing half‐cycles intensifies turbulence due to enhanced vortex interactions and flow separation at the diverged‐outlets. Longer wavy ducts are shown to increase flow acceleration, resulting in greater output velocities and more turbulent‐kinetic‐energy production. Wave‐period plays a crucial role in determining turbulent intensity, with amplitude

On a notion of entropy in coarse geometry
Topological Algebra and its Applications, 2019 The notion of entropy appears in many branches of mathematics. In each setting (e.g., probability spaces, sets, topological spaces) entropy is a non-negative real-valued function measuring the randomness and disorder that a self-morphism creates. In this

Optimal deployment of indoor wireless local area networks
Networks, Volume 81, Issue 1, Page 23-50, January 2023., 2023 Abstract We present a two‐phase methodology to address the problem of optimally deploying indoor wireless local area networks. In the first phase, we use Helmholtz's equation to simulate electromagnetic fields in a typical environment such as an office floor.

Duality relation among the Hamiltonian structures of a parametric coupled Korteweg-de Vries system
Open Physics, 2016 We obtain the full Hamiltonian structure for a parametric coupled KdV system. The coupled system arises from four different real basic lagrangians. The associated Hamiltonian functionals and the corresponding Poisson structures follow from the geometry ...
