Experimental investigation of pressure disturbances influence on a parallel flow of viscous immiscible liquids in a T-shaped microchannel
In the present paper pressure disturbances influence on parallel flow of immiscible liquids, viz. castor oil and paraffin oil, in a T-shaped microchannel with 320 um hydraulic diameter is studied experimentally. Pressure disturbances with sinusoidal and meander wave shape were applied at different f...

| description | In the present paper pressure disturbances influence on parallel flow of immiscible liquids, viz. castor oil and paraffin oil, in a T-shaped microchannel with 320 um hydraulic diameter is studied experimentally. Pressure disturbances with sinusoidal and meander wave shape were applied at different frequencies and pulse ratio to the flow of carrying phase, dispersed phase or both of them simultaneously. It was shown that pressure disturbances can lead to the transition to the slug flow. A parameter taking into account signal amplitude and frequency was introduced for flow map construction. Slug length and velocity was measured for all regimes studied. |
