摘要：

An experimental investigation was carried out for predicting the critical heat flux (CHF) of steady boiling,for a round subcooled water jet impingement on the flat stagnation zone. The experimental data were measured in a steady nucleate boiling state. Three main influencing parameters, i.e., subcooling, impact velocity and jet nozzle size were widely changed and their effects on the critical heat flux were systemically studied. An empirical correlation was obtained using the experimental data over a wide experimental range,for predicting the critical heat flux of steady boiling for a round subcooled water jet impingement on the flat stagnation zone.
