Modeling the capacitive deionization batch mode operation for desalination [PDF]

Journal of Industrial and Engineering Chemistry, 2014
This research article published by Elsevier, 2014Capacitive deionization (CDI) is an emerging desalination technology in which saline water flows through a pair of polarized/biased electrodes. The cations and anions are attracted towards the negative and

Control system design for steady state operation and mode switching of an engine with cylinder deactivation

Proceedings of the 2003 American Control Conference, 2003., 2004
Over the past decades, government legislations have placed increasingly stringent standard on numerous aspects of automotive performance; with safety and exhaust emissions being two of the most dramatically affected. Fuel economy standards (passenger car CAFE), however, have not increased since 1986.

Steady-state mode of operation of the countercurrent reactor. Liquid-liquid heterogeneous system

Russian Journal of Physical Chemistry B, 2014
A two-temperature model of the countercurrent plug-flow reactor for two chemically interacting liquids, the dispersion (continuous) media and dispersed phase, is developed. It is shown that there is a critical velocity of the dispersion medium that delimits two types of steady-state modes.

Steady-state Thermal Analysis of Fault-tolerant PMSM During the Open-phase Mode of Operation

In this paper, the initial outline of lumped-parameter thermal network and steady-state thermal finite element analysis for the fault-tolerant permanent magnet synchronous machine is demonstrated. The calculations show that the faulty operational mode with two open phases leads to substantial overheating of the machine when the need for the constant or

An NMR Imaging Study of Steady-State and Periodic Operation Modes of a Trickle Bed Reactor

Topics in Catalysis, 2009
NMR imaging has been applied to study the steady-state and the periodic operations of a functioning trickle bed reactor. It has been revealed that under conditions of the continuous supply of a liquid reagent to the catalyst bed, the bed was mostly filled with the liquid phase and was characterized by the uniform and stationary distribution of a liquid

Prediction of steady-state operating modes in recycle reactive-distillation systems using the mode of infinite separation efficiency

Theoretical Foundations of Chemical Engineering, 2009
The possibility of using the assumption of infinite separation efficiency for the prediction of steady-state operating modes in recycle reactive-distillation processes is analyzed. It is shown that whether the steady-state operating modes is feasible can be decided by analyzing the detailed pattern of the equilibrium phase diagram for the reacting ...

Implementation of an adaptive controller for the startup and steady‐state running of a biomethanation process operated in the CSTR mode

Biotechnology and Bioengineering, 1991
AbstractAn adaptive control algorithm has been implemented on a biomethanation process to maintain propionate concentration, a stable variable, at a given low value, by steering the dilution rate. It was thereby expected to ensure the stability of the process during the startup and during steady‐state running with an acceptable performance. The methane

Compatible operation of the power system for steady state and pulse modes in a magnetic torus KT-5D

Review of Scientific Instruments, 2006
Compatible operation of steady state mode and pulse mode is realized in the KT-5D device. New power supplies with the operation control systems for the steady state toroidal magnetic field as well as for the vertical field are added, and the rf wave injection systems for sustaining steady state plasmas are upgraded.

Approximation of Magnetizing Inductance Curve of Self-exited Induction Generator for Investigation of Steady-state Operation Modes

2020 IEEE 7th International Conference on Energy Smart Systems (ESS), 2020
This paper describes approximation methods of induction machines magnetizing curve on self-excited induction generator example. Induction generators manufacturers don't provide sufficient information about their machines magnetizing curve, also induction machine idle mode test do not provide information about possible range of magnetizing current ...
