Abstract
The flow control of NaCl aqueous solution was examined by applying gas–liquid interface deformation induced by magnetic fields. Detailed studies of the dependence of flow velocity and concentration on the change in flow rate were carried out. In this experiment, with a flow on the order of 100 ml/min, the change in flow rate was measured under magnetic fields of up to 10 T. The flow rate decreased due to gas–liquid interface deformation at magnetic fields of about 6 T or more; the decrease in flow rate was approximately 23% at most. The change in flow rate was dependent on the flow velocity but not on the concentration. In addition, the possibility of using gas–liquid interface deformation induced by magnetic fields as a new means of controlling the flow of NaCl solution without contact was discussed.
