Void fraction predictions in forced convective subcooled boiling of water between 10 and 18 Mpa

Forced convective subcooled boiling is of interest for many industrial applications, especially as a possible heat transfer regime in the core of pressurized water reactors (PWR). Due to practical interest, R12 was used as a testing fluid to simulate water between 10 and 18 MPa. This article presents a study of the forced convective subcooled boiling of R12 based on previous models and new physical considerations. The axial void fraction profile is determined and compared to R12 experimental data obtained on the DEBORA loop at CEA/Grenoble.
