摘要：

An experimental investigation has been made on flow instability and boiling crisis in a 50 mm×2 mm parallel rectangular channels at the pressure of 12~15 MPa. In the experiment, it has been found that the thermal parameter range of boiling crisis was extended, while the flow instability zone was reduced with the increase of pressure and mass velocity. And the boiling crisis curve and flow instability boundary line was drawn in Npch-Nsub pictures to analyze the effect mechanism of the thermal parameters on distribution regions. © 2016, Yuan Zi Neng Chuban She.
