Calculate dimensionless numbers (Reynolds, Péclet, Damköhler) and analyze species transport in microfluidic flow cells and biosensors.
Understanding Mass Transport in Microfluidics
Mass transport behavior at the electrode-electrolyte interface governs the performance of electrochemical flow cells, electrolyzers, and microfluidic biosensors. Key dimensionless numbers include:
- Reynolds Number (Re): Characterizes fluid flow regimes (laminar vs. turbulent) within microchannels.
- Péclet Number (Pe): Quantifies the ratio of advective transport rate to diffusive transport rate.
- Damköhler Number (Da): Compares the chemical/electrochemical reaction rate to the mass transfer rate.
