Analytical calculation of the flow superposition effect on the power consumption in oscillatory baffled reactors

, 2021
The aim of this communication is to clarify some aspects related to the power consumption in continuous Oscillatory Baffled Reactors (OBRs). The first aspect studied is the effect of the flow superimposition on the power consumptions associated to the ...

Experimental investigation of dryout phenomena under oscillatory flow conditions

Heat Transfer, 2022
In water‐cooled nuclear reactors, the maximum power which can be extracted from the core is limited by critical heat flux (CHF). CHF in the high‐quality region is known as dryout.

Experimental Evaluation of Two-Phase Heat Transfer Coefficient Under Oscillatory Flow Conditions and Correlation Development

Journal of Nuclear Engineering and Radiation Science, 2022
Natural Circulation Boiling Water Reactors (NCBWRs) are prone to flow instabilities. Due to instabilities, heat transfer deteriorates. However, the extent to which the heat transfer coefficient (HTC) deteriorates is not well established. In the present

Solids flow pattern in continuous oscillatory baffled reactor

Chemical Engineering and Processing - Process Intensification, 2019
Abstract Transition from batch to continuous processing is an attractive alternative for the production of pharmaceutical, fine and bio chemicals. In a number of such industrial reactions or separations, a solid phase is present either as a reactant, product or catalyst. Instead of conventional continuous reactors, the utilization of oscillatory flow

Operation and Optimization of an Oscillatory Flow Continuous Reactor

Industrial & Engineering Chemistry Research, 2001
Oscillatory flow reactors (OFRs) are a novel type of continuous reactor, in which tubes fitted with orifice plate baffles have an oscillatory motion superimposed upon the net flow of the process fluid. The combination of baffles and the oscillatory motion creates a flow pattern conducive to efficient heat and mass transfer while maintaining plug flow ...

Turbulent flow modeling in continuous oscillatory flow baffled reactor using STAR CCM +

2019
A detailed transient tridimensional CFD model of the turbulent flow of liquid phase inside of 26 mm diameter continuous oscillatory baffled reactor (COBR) was developed using STAR CCM+ software. The model considered a large number of COBR cavities separated with single-orifice baffles.
