FIGURE 3-6 Flow across the circular Tube (unit : m)<br />

External flow (see Figure 3-6) correlation for Nusselt number, Eq.3-10, is plot<br />

against the Reynolds number and compared with the values obtained by CFDsimulation.<br />

The result is shown in Figure 3-7. The dot line is empirical formula while<br />

the line is the numerical results from CFD-simulation. The results agree very well.<br />
