NU_MCADAMS

This function calculates a Nusselt number for supercritical turbulent internal flow using the McAdams-style power-law form. It uses Reynolds and Prandtl numbers with no additional property-ratio correction terms.

Nu = C\,Re^{m}Pr^{n}

Excel Usage

=NU_MCADAMS(Re, Pr)

Re (float, required): Reynolds number with bulk fluid properties (-).
Pr (float, required): Prandtl number with bulk fluid properties (-).

Returns (float): Nusselt number with bulk fluid properties (-).

Example 1: McAdams correlation example

Inputs:

Re	Pr
100000	1.2

Excel formula:

=NU_MCADAMS(100000, 1.2)

Expected output:

261.384

Example 2: McAdams correlation lower Reynolds number

Inputs:

Re	Pr
50000	1

Excel formula:

=NU_MCADAMS(50000, 1)

Expected output:

139.567

Example 3: McAdams correlation mid Reynolds number

Inputs:

Re	Pr
200000	0.8

Excel formula:

=NU_MCADAMS(200000, 0.8)

Expected output:

386.96

Example 4: McAdams correlation higher Reynolds number

Inputs:

Re	Pr
700000	1.5

Excel formula:

=NU_MCADAMS(700000, 1.5)

Expected output:

1355.57
