Annular flow region

In the inverted annular flow region, it is assumed that the vapor generation near the wall occurs fast enough that the velocities of the two phases are about equal, or S = (uGluL) 1. [Pg.212]

Modeling of Annular Flow Region. Continuing with this simple example, we next consider the annular flow region. The balanced equation for this region has the form... [Pg.255]

We know that the tubular die flow channel is composed of a series of more or less annular flow regions, which are straight, tapering, of almost uniform cross section, or interrupted... [Pg.722]

Consider the annular flow region / , < r < Ra, 0 < z < L, and 0 <6 < 2n. An incompressible Power Law fluid is flowing under steady and isothermal conditions because of the pressure drop AP = P0 PL. The flow is assumed to be fully developed. Under these assumptions the z-component momentum equation becomes... [Pg.724]

The average of tiiese two pressiwe drops resulting from die interpolation based on G and x represents die two-phase pressiwe drop for the d ansition region data point. This model predicts 87% of die data widiin 20%. It should be noted diat diese predictions include not only die annular flow region, but also die mist and disperse-wave flow data, whereas die preliminary model of Garimella et al. [Pg.284]

The implication is that correlations similar to those used for pool boiling can be used for multicomponent boiling at low-quality or subcooled conditions. For the annular flow region, predictions based on the models described in the preceding section should give reasonable results based on mean physical properties of the mixture. [Pg.1118]

Answer by author No annular flow was observed during the test series described in this paper. Flow velocities were such that we did not operate for any appreciable period of time in the annular flow region mapped on Fig. 2. [Pg.333]

A typical wire coating die was shown in Figure 1.4. The design that is shown there is somewhat beyond our capabilities at this point. For this reason we consider only the annular flow region as shown in Figure 2.10. We make the following assumptions ... [Pg.17]
