Experimental investigation of the optimization of stilling basin with shallow- water cushion used fo
Energy dissipations induced by the hydraulic jump and the trajectory jet are the most widely known as the two dissipation modes at the downstream of flood disch
This paper proposes a method for determining the gas recovery of water-drive gas reservoirs. First, the water influx coefficientB in the theoretical formula=(1)
Exact analytical solutions for moving boundary problems of one-dimensional flow in semi-infinite por
By defining new dimensionless variables, nonlinear mathematical models for one-dimensional flow with unknown moving boundaries in semi-infinite porous media are
The flow rate of the oil-water horizontal flow is measured by the combination of the turbine flow meter and the singlebeam gamma ray densitometry. The emphasis
