Flow averaged concentration
Webmixing cup (flow averaged) concentration and clearly there is a discrepancy between equation (11a) and eq (10a).. You should examine the deviation of eq (11a) compared to eq (10a) and plot it as a function of Da. The needed exponential integral are tabulated by Abramowitz and Stegun (Handbook of Mathematical Functions, Dover Publ. 1964). WebNov 29, 2016 · The averaged concentration of free drug increases in the lumen due to flow pulsatility while a reverse trend is observed in the tissue. Additionally, modelling results also indicate that time-dependent release of drug in stent-based delivery diminishes the averaged concentration of both drug forms as compared to constant release kinetics ...

When an undersaturated reactive fluid is flowing in a fracture, the dissolution process will alter the flow paths locally. Dissolution patterns grow slowly, but they may lead to a dramatic reorganization of the flow. Here, we study dissolution in a radial geometry, which is …
