Numerical Study on Flow Characteristics of Synthetic Jet with Slot Exit

Abstract

The flow characteristics of synthetic jet depending on rectangular and circular jet exit configuration are investigated using numerical computation with cross flow. In rectangular slot, synthetic jet generates the strong vortex, however, supply fewer momentum and effectiveness of flow control is reduced along flow direction. In circular slot, regular vortex is formed from slot center to end and developed in flow direction. It affects the wider region than rectangular slot. The distribution of wall shear stress is considered in order to indicate the effectiveness of flow control device for flow separation delay. As a result, circular slot is a more suitable candidate for delaying flow separation.본 연구는 방위사업청과 국방과학연구소의 지원(UC100031JD), 슈퍼컴퓨팅센터(KSC-2010-CI-0030), 항공 우주 신기술 연구소의 지원으로 수행되었음.OAIID:oai:osos.snu.ac.kr:snu2011-01/104/0000004648/18SEQ:18PERF_CD:SNU2011-01EVAL_ITEM_CD:104USER_ID:0000004648ADJUST_YN:NEMP_ID:A001138DEPT_CD:446CITE_RATE:0FILENAME:Synthetic_Jet_출구_형상의_변화에_따른_유동_특성_파악을_위한_수치적_연구.pdfDEPT_NM:기계항공공학부EMAIL:[email protected]:
