Ideal Tube Bank Correlations for Heat Transfer and Pressure Drop

3.3.7 Ideal tube bank correlations for heat transfer and pressure drop

The shell-side method is based on the heat transfer ji factor and the friction factor fi from data on ideal tube banks and then correcting these values for the nonidealistics of the flow in a baffled exchanger. Pressure drop and heat transfer in ideal tube banks are described in Section 146 and Section 170, respectively. However, the development of the Delaware method was based on a specific set of ideal tube bank data with geometric similarity to shell-and-tube heat exchanger practices. For this reason it appears preferable to use the same set of graphs as a basis. These are presented in Figure 1, Figure 2, and Figure 3 as functions of the layout angles and pitch ratios Ltp/Dt, covering the industrial range of practical values.

Figure 1 Ideal tube bank ji and fi factors for 30° staggered layout [Res from Equation 251.25]

Figure 2 Ideal tube bank ji and fi factors for 45° staggered layout [Res from Equation 251.25]

Figure 3 Ideal tube bank ji and fi factors for 90° in-line layout [Res from Equation 251.25]

No attempt is made here to correlate the data, and the user is expected to read the corresponding value of ji and fi as functions of the Reynolds number Res, from the graphs. For possible computer application, however, a simple set of constants is given in Table 1 for a curve fit of the following form:
