5.6 Cage Size Results
Maximum possible cage size is determined by the point at which the cage wrinkles.
Figures 5.13 and 5.14 show the maximum cage diameter results by tube diameter for the
top-flow and side-flow cases respectively. Slight pressure effects are noted between the
pressure groups of the top-flow case, but are neglected to form one linear increasing
trend. The trend generally shows that, independent of pressure, as diameter increases, the
maximum possible cage diameter increases for top-flow conditions. The side-flow case,
however, has significant pressure effects visible in Figure 5.14. Each pressure group is
plotted with an increasing linear trend, but a distinct slope and y-intercept. Within each
