Critical heat flux (CHF) has been measured on rectangular heated surfaces 40 and 80 mm in length and 20 mm in width during saturated forced boiling with a plane jet. The experiments were carried out at jet velocities of 3 to 15 m/s and system pressures of 0.1 to 0.4 MPa. The experimental result shows that there is no difference in occurrence of the CHF between upward-and downwardfacing heated surfaces. It is found that no existing correlation can predict the CHF over a wide range of pl/pg from pl/pg=6.6 to 1 603. A revised correlation is proposed to give the CHF over the range of pl/pg.
