H_BOIL_HUANGSHEER

This function estimates boiling heat transfer in plate exchangers using the Huang-Sheer correlation. It depends on thermophysical properties, imposed heat flux, and saturation temperature rather than detailed exchanger geometry.

The correlation follows the structure:

h = f\left(k_l, q, T_{sat}, H_{vap}, \alpha_l, Pr_l, \rho_l, \rho_g, \sigma, \theta\right)

where bubble-scale effects are embedded in the model and the function returns h in W/m^2/K.
