Oil flows into a glass tube during the imbibition phase of the experiment. The oil is initially stored in a reservoir on the right side of the tube (not visible). When the reservoir is open, the oil spontaneously flows into the tube, driven by interfacial/capillary effects. The Gaucho Lung investigation will study fluid transport within gel-coated tubes to learn more about treatment programs for respiratory distress syndrome and develop new contamination control strategies.
