Evolution of Streaming Potential in a Finite Length Microchannel
Bibliographic record
Abstract
Electrokinetic (EK) flow, i.e., flow of an electrolyte in narrow capillaries driven by the combined influence of electric field and pressure, is of significant interest in microfluidic devices. Review of literature reveals that most studies on microchannels are either for steady state conditions or infinite length microchannels. In this work, we examine the development of a transient streaming potential for pressure-driven EK flow in a finite length microchannel. A transient numerical simulation of ion transport leading to the development of a streaming potential across a finite length circular cylindrical microchannel connecting two infinite reservoirs is presented. The solution based on finite element analysis shows the transient development of ionic fluxes, currents, and the streaming potential across the channel. The simulation results show that the streaming potential across the channel is predominantly set up at the timescale of the developing convective transport, while the equilibrium ion concentrations are developed over a considerable longer duration.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
