    A better alternative is to reduce the flow rate in the experiments, and include capillary pressure in the analysis. In this work, we use the fact that a reduced flow rate will lead to a spreading of the shock front. The front will translate with a fixed shape (denoted as a traveling wave or a stabilized capillary zone1). We propose a new.

The test section flow can be adjusted to the required value with the help of control valves at the inlet and outlet. Demineralised water was used as the working fluid. Because of closed loop operation, the water gets heated up due to the energy input by the pumps. A cooler was provided to maintain the loop temperature at the required.

    Suppose I have a capillary tube inside a water trough and water level raises inside the tube till point 'x'.Now if I break the tube below this level 'x', will the water keep on flowing forever because it will keep sucking water till the point x or something else will happen?Help.
