Abstract
In the present paper the thermo-solutal-capillary (Marangoni) migration of a methanol liquid drop, which exhibits a miscibility gap in solution with cyclohexane, is studied. The simulation starts from the drop injection in a closed cavity with differentially heated end-walls. The paper is devoted to the preparation of a MAXUS 5 sounding rocket space experiment. The main goal of the analysis is to clarify if and how the dissolution process affects the drop migration. The numerical code is based on the modern level-set technique. Non steady and steady migration speeds are determined for different drop radii and temperature differences during the whole drop migration along the cavity axis.
