Accurate Multi-physics Numerical Analysis of Particle Preconcentration Based on Ion Concentration Polarization
Zirui Li, Wei Liu, Yudan Zhu +3
This paper studies mechanism of preconcentration of charged particles in a straight micro-channel embedded with permselective membranes, by numerically solving coupled transport eq…
Three dimensional free-surface flow over arbitrary bottom topography
Nicholas R. Buttle, Ravindra Pethiyagoda, Timothy J. Moroney +1
We consider steady nonlinear free surface flow past an arbitrary bottom topography in three dimensions, concentrating on the shape of the wave pattern that forms on the surface of…
Efficient computation of two-dimensional steady free-surface flows
Ravindra Pethiyagoda, Timothy J. Moroney, Scott W. McCue
We consider a family of steady free-surface flow problems in two dimensions, concentrating on the effect of nonlinearity on the train of gravity waves that appear downstream of a d…
Calculating groundwater response times for flow in heterogeneous porous media
Matthew J Simpson
Predicting the amount of time required for a transient groundwater response to take place is a practical question that is of interest in many situations. This time scale is often c…
Accurate and efficient calculation of response times for groundwater flow
Elliot J. Carr, Matthew J. Simpson
We study measures of the amount of time required for transient flow in heterogeneous porous media to effectively reach steady state, also known as the response time. Here, we devel…
The effect of surface tension on steadily translating bubbles in an unbounded Hele-Shaw cell
Christopher C Green, Christopher J Lustri, Scott W McCue
New numerical solutions to the so-called selection problem for one and two steadily translating bubbles in an unbounded Hele-Shaw cell are presented. Our approach relies on conform…
