To estimate the hydrodynamic force in the quasi-steady flow phase, we have adopted the hydrostatic force equation by incorporating bore height at the structure front (hf) and bore height at the structure back (hr). A simplified semi-analytical method is proposed based on continuity and momentum...
With the bleed-off operation, the wellhead pressure dropped to the hydrostatic fluid pressure after four days. After that, the well remained open, and 3400 m3 water flowed back over a period of 14 months. During the injection operation, when the injection pressure was below 8.0 MPa (80 bars...

Another advantage of using solely mechanical foam treatment is the enhancement of oxygen transfer in microbial fermentations, whose productivity is rather often limited by the availability of dissolved oxygen in the broth. According to the well-known equation for the oxygen transfer rate. ...
(i.e., with depth). Figure2ashows only PCO2versusT, howeverpandTvalues used in simulations are correlated, since we assume hydrostatic and geothermal depth-dependence. Elevated PCO2of groundwater in deep-seated aquifers is maintained over time by large CO2fluxes originating, for example, from ...
Whether a solar eruption is successful or failed depends on the competition between different components of the Lorentz force exerting on the flux rope that drives the eruption. The present models only consider the strapping force generated by the backgr
The total pressure drop ∆P between two points in a vertical channel can be written as ∆ P = ∆ Ph + ∆ Ptp + ∆ Pac (13) which is the sum of the hydrostatic head ∆Ph, the two-phase frictional pressure drop ∆Ptp, and the accelerational pressure drop ∆Pac. The ...
