The effects of reaction delay in the Nagel-Schreckenberg traffic flow model
The European Physical Journal B, 2006This paper studies a new model, which considers the effects of drivers reaction delay in the Nagel-Schreckenberg model. We studied the traffic flow properties in the new model under both periodic and open boundary conditions. The fundamental diagram, spatio-temporal patterns, density-density correlation functions, relaxation time, and distance headway ...

Reynolds number effects on mixing and reaction in a turbulent pipe flow
Chemical Engineering Science, 2001Abstract A new Lagrangian mixing model is presented that describes the turbulent mixing of reacting scalars as a cascade process from large to small scales. The model is derived by applying guidance of Eulerian multi-scale mixing models. Compared to these models, the essential advantage of the derived Lagrangian model is given by the fact that ...

Non-Newtonian fluid effects on surface reactions in a microfluidic flow cell
AIP Conference Proceedings, 2012Mass transfer over a reactive surface in microfluidic flow cells plays a key role in understanding biomoleculer interactions and diagnosis of small molecules for biomedical and environmental applications. The effects of Non-Newtonian power law fluid on the binding reaction kinetic of immunoglobulin G in a flow cell are analyzed in this study. Governing

ACS Applied Materials & Interfaces, 2015
Low-cost microfluidic devices are desirable for many chemical processes; however, access to robust, inert, and appropriately structured materials for the inner channel wall is severely limited. Here, the shear force within confined microchannels was tuned through control of reactant solution fluid-flow and shown to dramatically impact nano- through ...

Flow Field and Non-Isothermal Effects on Diffusion, Convection, and Reaction in Permeable Catalysts
Industrial & Engineering Chemistry Research, 1995We analyze non-isothermal effects on the efficiency of large-pore catalyst particles, where intraparticle convection may be important. The particle permeability is taken into account by studying the flow field within the particle simultaneously with the mass and the energy transport processes.

Heterogeneous-homogeneous reactions and melting heat transfer effects in flow with carbon nanotubes
Journal of Molecular Liquids, 2016Abstract The communication here addresses the impact of heterogeneous-homogeneous reactions in boundary layer flow of nanofluid saturating porous medium. The stretching cylinder caused the flow in presence of melting heat transfer. Analysis for single-wall carbon nanotubes (SWNTs) and multi-wall carbon nanotubes (MWNTs) is explored. Water is taken as

Space-charge effects in flowing-afterglow data analysis for negative-ion/molecule reactions
International Journal of Mass Spectrometry and Ion Physics, 1981Abstract In positive-ion/negative-ion plasmas, the space-charge fields (ambipolar fields) in the flow tube vary as the ion/molecule reaction proceeds if the value of the diffusion coefficient of the product ions is not equal to that for the reactant ions.

Effect of boundary reaction on solute dispersion in pulsatile flow through a tube
Journal of Fluid Mechanics, 1992This paper examines the streamwise dispersion of passive contaminant molecules released in a time-dependent laminar flow through a tube in the presence of boundary absorption or a catalytic wall reaction, which causes a depletion of contaminant in the flow.
