HEDH_TABOREK

This function calculates nucleate boiling heat transfer coefficient with the HEDH-Taborek correlation using saturation and critical pressure with either excess wall temperature or heat flux.

In general form:

h = f\left(P, P_c, \Delta T_e\right) \; \text{or} \; h = f\left(P, P_c, q\right)

It is used as a pressure-based empirical alternative for pool-boiling coefficient prediction.

Excel Usage

=HEDH_TABOREK(P, Pc, Te, q)

P (float, required): Saturation pressure of fluid (Pa).
Pc (float, required): Critical pressure of fluid (Pa).
Te (float, optional, default: null): Excess wall temperature (K).
q (float, optional, default: null): Heat flux (W/m^2).

Returns (float): Heat transfer coefficient (W/m^2/K), or an error message if invalid.

Example 1: Reference example with excess temperature

Inputs:

P	Pc	Te
310300	2550000	16.2

Excel formula:

=HEDH_TABOREK(310300, 2550000, 16.2)

Expected output:

1397.27

Example 2: Reference case with heat flux

Inputs:

P	Pc	q
310300	2550000	25000

Excel formula:

=HEDH_TABOREK(310300, 2550000, 25000)

Expected output:

1497.9

Example 3: Lower pressure with excess temperature

Inputs:

P	Pc	Te
150000	2550000	10

Excel formula:

=HEDH_TABOREK(150000, 2550000, 10)

Expected output:

178.873

Example 4: Higher pressure with heat flux

Inputs:

P	Pc	q
600000	2550000	35000

Excel formula:

=HEDH_TABOREK(600000, 2550000, 35000)

Expected output:

2803.29
