Dear Mr. Amine,

thank you!

You are right. I tried the computation of HTC with constant Nusselt number and, as you said, only specification of HTC in terms of "k*Nu/d" was enough. Maybe there is a specific reason why the implementation of "Ranz-Marshall" model requires also addition of interface area.

Regarding "Geo-Reconstruct", I found it as a suitable in the case of planar surface evaporation. This is shown in the attached figure.

Best regards,

Alen

P.S.
The physical properties (density, specific heat, thermal conductivity and viscosity) of water-liquid and water-vapor are taken from [1]. Also, the analytical solution shown here is extracted from [1] using [2].
