An equation was derived which gives the value of Δt in terms of the average boiling point t aω and the total pressure π(1) calculated for a bubble point equal to t aω For mixtures containing up to four components, a simple formula was found to give quite satisfactory answers. When...
Based on the analysis above, we set the bubble interface temperature at the bottom of the bubble around the nucleation region to reach the boiling point (373 K) in the space microgravity environment. Then we conducted the simulation of the terrestrial model with the same heating power and ...

Vapor density and enthalpy are functions only of pressure: qG ¼ qG;sat ðPÞ HG ¼ hG;sat ðPÞ Finally, a, P, uG, uL, and HL are considered as the depen- dent variables in Equation (37). The set of equations was solved for the operating conditions summarized in Table ...
Even though it is not used in the above equations, the pressure at the critical point is 227.46 kPa44. With the density and temperature expressed in a reduced form, all parameters in the virial coefficients are dimen- sionless. The optimally fitted parameter values are summarized in ...
Assuming the liquid phase is perfectly wetting, the capillary pressure in (3b) is modeled by the Young–Laplace equation, pc=2γr, (10) where γ is the surface tension and r is the radius of the gas bubble. We assume that the gas phase forms as a single bubble in the pore and th...
Thebubble point pressureis 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=(4γcosθ)...
