The structure of turbulent shear induced countercurrent flow

, 1988
Summarization: Countercurrent flow is a generalized plane Couette flow in which a shear-induced drift current is opposed by a pressure-driven return flow such that the resulting mass flux is zero.

Batch Enzymatic Hydrolysis of Pretreated Corn Stover and Improvements with Countercurrent Saccharification [PDF]

, 2015
Enzymatic saccharification of non-food biomass, such as lignocellulose, can produce sugars. Sugars are the common feedstock for bioethanol, which can be substituted for transportation fuel and address the shortage of fossil fuels.

Batch Simulation of Multistage Countercurrent Extraction of Uranium in Yellow Cake from Monazite Processing with 5% TBP/Kerosene

, 2014
In the processing of monazite ore to separate uranium, thorium and rare earth elements composed in the ore, uranium is first extracted and precipitated in the form of sodium diuranate (Na2U2O7) or yellow cake.

Over 'countercurrent-distribution'

, 1953
Après quelques remarques générales sur l'extraction par contre-courant, l'auteur décrit principalement la C.C.D. de Craig. Les différents appareils en usage sont décrits brièvement ainsi que les principes théoriques à la base de cette nouvelle méthode de

Dynamic Modeling and Simulation of a Countercurrent Molten Carbonate Fuel Cell (MCFC) with Internal Reforming

, 2002
A dynamic mathematical model for a countercurrent MCFC with direct internal methane reforming is introduced. It allows for the simulation of the gas phase compositions and flows, the temperatures in gas and solid phases, the cell voltage, and the current

A Study of a Two-Phase Heat Transfer Mechanism in a Vertical Sintering Cooling Furnace

Energies
In order to explore the law of gas–solid countercurrent cooling heat transfer in a vertical sinter cooling furnace at a high temperature, based on the Euler model and the local non-thermodynamic equilibrium theory, an exergy efficiency model was built to
