Figure 2.35: Two different transition profiles of trumpet: streamline <strong>and</strong> multi-line<br />
The first image in Figure 2.36 shows the velocity magnitude in a few cross-sections in the trumpet with<br />
smoothly curved transition. The second image in Figure 2.36 shows the velocity magnitude in the<br />
trumpet built with multi-linear panels. The smooth curve produces a fairly uni<strong>for</strong>m velocity throughout<br />
the cross-section at the end of the trumpet. The trumpet with multi-linear transition produces a velocity<br />
distribution that is similar to that by a smoothly curved trumpet in general. However, some local high<br />
velocity near the corner is observed. The local high velocity is especially clear <strong>for</strong> the last three sections<br />
shown in Figure 2.36.<br />
