WebThe sessile drop is the standard arrangement for optical measurement of the contact angle using drop shape analysis. Background In the case of the static contact angle, the deposited drop lies on the surface of a solid. WebMay 9, 2024 · Numerous sessile drop and micro-computed tomography (micro-CT) studies have been conducted to quantify geologic carbon storage formation wettability by measuring static contact angles (θ); however, the influence of pore geometry remains unknown. In this work, six sandstones (Bandera Brown, Berea, Bentheimer, Mt. Simon, Navajo, and …
