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 ...
Study on transient ice formation of laminar flow inside externally supercooled rectangular duct
(2000-12-01)
The transient process of solidification of laminar liquid flow (water) submitted to super-cooling was investigated both theoretically and experimentally. In this study an alternative analytical formulation and numerical ...
Drag reduction phenomenon in viscous oil-water dispersed pipe flow: Experimental investigation and phenomenological modeling
(WILEY-BLACKWELLHOBOKEN, 2012-09)
An experimental study on drag-reduction phenomenon in dispersed oil-water flow has been performed in a 26-mm-i.d. Twelve meter long horizontal glass pipe. The flow was characterized using a novel wire-mesh sensor based on ...
