Petrosky and Farshad’s gas solubility equation, Eq. (4.28), can be solved for the bubble point pressure to give (4.36)pb=112.727Rs0.577421γg0.843910x–1391.051 where the correlating parameter, x, is as previously defined by the following expression: x=7.91610–4API1.5410–4.56110–5T–4601.39...
Correlation of the bubble point pressures with the PRSV equation of state and WS mixing rules was to within an average of 2.391% absolute deviation in pressure for all systems, which is considered to be sufficient for design of spray devices with propellants that have low global warming ...

An equation was derived which gives the value of Δt in terms of the average boiling point taω and the total pressure π(1) calculated for a bubble point equal to taω For mixtures containing up to four components, a simple formula was found to give quite satisfactory answers. When the...
(27), if the BHP is above the bubble point pressure, well productivity is only affected by permeability changes due to fracture pressure. If BHP is below the bubble point pressure, oil degassing in the bottom-hole region has an additional impact on well productivity. At \({\alpha }_{k}...
This work presents a new correlation equation that would reasonably reflect the two-phase theory of fluidization. Although the two-phase theory has the simplest form for calculation it tends to overpredict it. This may affect the prediction of volume fractions and superficial gas velocities for othe...
pressure phase equilibrium states, a Leung-Griffiths model modified for ternary mixtures was used to calculate pseudo-data. This ternary mixture model was also used to calculate new values for the critical point, maxcondenbar and maxcondentherm for air. The calculated properties at the maxconden...
The derivation of effective equations for pressure wave propagation in a bubbly fluid at very low void fractions is examined. A Vlasov-type equation is der... SMEREKA,PETER - 《Journal of Fluid Mechanics》 被引量: 34发表: 2002年 Derivation of the modified diffusion equations in a gas mixture...
The bubble point pressure is a direct measurement of the largest pore in the membrane. Based on the surface tension of the fluid in the membrane pores and the wetting angle of the membrane polymer, the diameter of the pore can be calculated using the Young–Laplace equation, ΔP=(4γ cos...
In the bubble point method, the pores of the membrane are completely wet with a liquid (phase 1) which is then displaced with air (phase 2). The Young–Laplace equation allows the maximum pore radius rp,max (m) to be calculated from the value of the transmembrane pressure ΔP (Pa) me...
