The thermal performance depends on r, on the compression rate, and on factor k = Cp/Cv (Cp: specific heat at a constant pressure and Cv: specific heat at a constant volume). In theory, considering that the ratio PCI/(1 + Va) for gasoline is 960 and for methane it is 836, the ...
Equation 6-106 is the radial diffusivity equation for compressible fluids. This differential equation relates the real gas pseudopressure (real gas potential) to the time t and the radius r. Al-Hussainy, Ramey, and Crawford (1966) pointed out that in gas well testing analysis, the constant-...
All other model input assumptions are held constant across scenarios. Two alternate electrification scenarios are run to explore how end-use demand affects the role of natural gas under different electric sector policy scenarios: Reference electrification (RefEl): The core scenarios of the analysis ...
Also, the parameters of the oxygen mass fractions are assumed to be constant and known. The governing equations for the remaining six states are as follows: $$\begin{aligned}{} & {} \dfrac{d}{dt} p_{im} = \dfrac{R_a T_{im}}{V_{im}}(W_c+W_{egr} - W_{ei}), \end{...
The chemical process was found to control the smallest particle size carbonation test, in very good agreement with the kinetic constant value proposed in ... LD Felice,PU Foscolo,L Gibilaro - 《International Journal of Chemical Reactor Engineering》 ...
The utility model provides a constant-air volume regulator and a combustor for improving the thermal efficiency of a gas water jacket furnace. The constant-air volume regulator comprises a cylindrical housing (171), wherein an elastic silicone bowl (22) is arranged in the housing (171); the ...
ΔPL=γ1Rdown−1Rup (2) whereRdownandRupare the radius of curvature of the gas part on porous sheet’s lower and upper sides, respectively. In this case, the lower gas is the bubble, and the upper gas is the trapped air film. Beca...
For the supplied gas phase (air), a pressure valve along with a metering system were utilized to deliver the air at a constant and stable flow rate. The liquid phase was pumped by a centrifugal pump from the water reservoir at room temperature and at atmospheric pressure via a regulator to...
However, the data considered here are all for air–water and so surface tension is essentially a constant. It can be seen that in the churn flow region the entrained fraction increases as the gas superficial velocity decreases. The position at which this increase takes place commences at higher...
