Figure 32b shows the vertical profile of the global annual mean Fe injection rate.
In particular, these important parameters include injection rate, mean spray angle, bulk in-cylinder instantaneous temperature and pressure, and residual gas fraction from a thermodynamic point-of-view.
The results show that, with the injection rate, mean particle diameter and critical restarting pressure gradient coefficient increasing, the ultimate oil recovery factor will increase first, and then decrease.
The effect of important reactor parameters such as superficial gas velocity, maximum stable bubble size, mean particle size, catalyst injection rate, monomer/comonomer feed ratio and temperature of the feed stream, on the dynamic and steady-state behavior of the FBR is investigated.
Figure 6 shows the required variations of the mean injection and production flow rates to achieve the shown optimized sweep efficiency.
It is well noted that the employed optimization scheme enhances the sweep efficiency before the obstruction at breakthrough by approximately 55%%. Figure 12 also shows the required variations of the mean injection and production flow rates to achieve the shown optimized sweep efficiency.
Then, the influences of injection rate, suspension concentration, mean particle diameter, critical threshold pressure gradient and permeability ratio in ultimate oil recovery factor and water-cut are studied.
IV contrast material was injected by means of an automated power injector with an injection duration of 20 s (maximum injection rate of 5 ml/s), and 20 ml of saline was subsequently injected at the same injection rate.
Engine loading (taken as brake mean effective pressure (BMEP)) is kept constant at 2.5 bar by adjusting the fuel injection rate.
The linked TOUGH2MP-FLAC3D simulator has been used to study the coupled hydraulic-mechanical responses to primary stresses, injection rate and reservoir permeability during CO2 injection and post-injection periods by means of 4 case studies.
