Turbulent flow in pulsed extraction columns with internals of discs and rings:Turbulent kinetic energy and its dissipation rate during the pulsation [PDF]
, 2009 Turbulent energy parameters of single-phase pulsed flow in an extraction column with internals of immobile discs and rings (doughnuts) are studied. Simulation results are obtained by resolution of Reynolds equations coupled with k–ɛ model of turbulence ...

AIChE Journal, EarlyView.Abstract Electrification of distillation offers a promising route to reducing scope‐1 emissions from one of the chemical industry's most energy‐intensive unit operations. However, conventional adiabatic columns are dynamically inflexible: Long, energy‐intensive start‐ups make shutdown and restart impractical under variable electricity prices and ...

Efficiency of epibenthic Renfro beam nets for sampling penaeid shrimp
Ciencias Marinas, 1994 The efficiency of a Renfro beam trawl net was tested in vegetated and nonvegetated habitats of Términos Lagoon, Mexico. The white shrimp, Penaeus setiferus (87%), predominated over the brown shrimp.

Complexity Analysis of Bubble Plumes in Power Law Fluids Based on Chaos Theory
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT In order to reveal the complexity of the internal flow of bubble plume in power law fluid, the flow characteristics and chaotic characteristics of plume are studied by experiment and theory. The chaotic characteristic parameters (correlation dimension D, K entropy, and Lyapunov exponent λ) of gas velocity under different superficial gas ...

Determinants of axial osmotic gradients in the differentiating countercurrent system [PDF]
, 1984 The renal medullary countercurrent system differentiates into its final segmental nephron function and geometry during perinatal development. The influence of these changes on the medullary longitudinal osmotic gradient cannot be evaluated by ...

Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Post‐harvest agricultural residues in Latin America are commonly underutilized, leading to greenhouse gas emissions and lost opportunities for bio‐based value creation. This study tests the hypothesis that decentralized, farmer‐scale pyrolysis technologies can deliver comparable agronomic benefits while exhibiting distinct techno‐economic and ...
