For a same fracture section, when the ratio of the maximum filled area to the fracture section area before grouting is less than 90%, the flow velocity presents an upward trend with the flow section decreasing due to the Venturi effect caused by the grouting stone. When the ratio of these...
In the reference case, the void fraction is nearly constant in case of pressure of 2 MPa in the steam separator drum, though the flow is not completely free of condensation, which is due to the presence of pressure drop even when the valve is fully open (Fig. 3). This effect is more...
Because the densities of oil and gas are different, the bubbles are moving upward by the buoyancy in the crude oil. Since the viscosity of crude oil is rather high, and the floating velocity of bubbles is very slow, the flow state is always in the laminar region. As a result, the ...
