Thermally Driven Instabilities of Liquid Jets

点击翻译按钮获取中文摘要

This research concerns the breakup of small diameter jets of liquid. Experimental research will be conducted on a water jet that has had its surface heated periodically along its length. The growth of perturbations imposed on the jet will be measured in order to establish the amplification rate as a function of wavenumber. Of particular interest is the ability to control the breakup process through variation in the frequency, amplitude and duty cycle of an imposed square wave heating cycle.
