According to the roles of mining fractures development and relief gas flow, a novel method for the comprehensive gas drainage was proposed and engineering practiced in the mining field, which includes long drilling boreholes, oblique crossed boreholes and upper corner flexible drainage pipelines.
If deterministic gas and power flow methods are used to analyze the natural gas and electricity coupled system, not only is there a large amount of calculation, but also it is difficult to obtain a detailed description of the overall situation of the system.
The present study, conducted in ARDS patients, compared the effects over time of a single static PV measurement – using the super syringe and the constant flow method – on gas exchange.
A coupled gas-particulate numerical model is presented using Finite Differences to solve for the gas flow with an Immersed Boundary Method (IBM) to represent the complex bucket and enclosure geometry in the model.
To reduce the large integration errors brought by traditional methods in gas flow measurement under complex flow field, artificial neural network, support vector machine and other intelligent algorithms have been put into use.
The gas flow is measured by pressure rise method using spinning rotor gauge (SRG).
This paper presents a simple, yet accurate, method of predicting gas flow rates for a specified choke size under sub-critical flow conditions through chokes.
2) For the first time, a unified probabilistic power and gas flow calculation based on the cumulant method is proposed to analyze the effect of uncertain factors on the natural gas and electricity coupled system.
Rather than altering the volume gas flow rate, we developed a new method of rotating a specially designed sample holder to evaluate the influence of the gas flow state on the microstructures and superconducting properties of YBCO films.
