Applicability of Analytical Models Many of the models discussed in the first two-phase flow block are especially useful for the bubbly flow regime (and into slug flow). The concept of two-phase averaged parameters, such as { α } and S , are most relevant in these regimes, as is φ 2 lo . At high mass flux and pressure, bubbly flow is well-modeled with the HEM. At lower mass fluxes and BWR pressures, the drift flux model is recommended in the bubbly regime.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
