Imbibition dynamics in a flattened triangular channel including corner film flow

HIGHLIGHTS

• What: The prediction of the wetting fluid invasion in such a configuration still requires an in-depth analysis, which is the focus of the present study. The aim of the present analysis is the derivation of quasi-analytical solutions for the dynamics of the bulk meniscus, including that of the wetting liquid film in the corners that are further compared with experimental data from Amyot . With the above material at hand, the analysis is now focused on two different cases of imbibition: first when a constant flow rate, Q0, is imposed at the channel inlet, which corresponds . . .
