Joline Marie Fan, 17, of Columbus, studied the drag reduction phenomenon created by the interaction of acoustic waves on the motion of mesobubbles in both reactive and non-reactive flow systems for her engineering project in the Intel Science Talent Search. Her previously patented "Gas Ejector" system design and its accompanying drag reduction application enable the production and injection of microbubbles into a gas-liquid system. Used in combination with an acoustic transducer in both vertical column and horizontal pipe flow systems, Joline was able to excite the mesobubbles attracted to the node region of the wave (unlike the smaller microbubbles), thereby increasing the bubbles' transport activity and the flow rate of the system. Her findings could increase efficiency of heating and cooling systems, chemical reactors and the de-oxygenation of water in fruit juice production. The daughter of Drs. L. S. Fan and Sue Weng, Joline is first in her class of 482 at Upper Arlington High School, where she is winner of numerous awards in music, fencing and debate. Co-author on two journal publications, Joline plans to attend Princeton, study chemistry and pursue a doctorate.
