ドーナツ型チャンネルを用いた電気浸透流の界面電流の測定 : 拡散二重層モデルによる評価(流体工学,流体機械)

Abstract

Based on diffuse double layer model, the definition of the interface current that flows in an electric double layer (EDL) is given and formulated. To meet the requirement that the experimentally measured interface current assuming that the EDL thickness being extremely thin coincides with the definition, a correction factor is introduced to compensate its simple assumption. The relationship between the interface current and the electroosmotic velocity is also given. Using the experimentally measured interface current and electroosmotic velocity, the effective temperature rise in EDL due to the joule heating by the interface current was estimated and the effect of the interface current on EDL was discussed.
