Résumé

An experimental study of single-phase and flow boiling heat transfer of a submerged microjet array was conducted with R134a. The staggered array of seventeen 112-microm. diameter orifices impinged onto a 1 x 1-mm heater. Boiling experiments were conducted with liquid subcoolings of 10, 20, and 30°C at jet velocities of 4, 7, and 10 m/s. Boiling was generally found to enhance heat transfer with a maximum heat flux of 590 W/cm2. However, temperature excursions occurred at low superheats and were found to be related to non-condensable gas content. [Reprinted with permission from Elsevier. Copyright, 2010].
