Abstract

Flow over a backward facing step has been one of important research field in fluid mechanics. By simulating the flow over a backward-facing step and analyzing the instability of fluid in different blowing and suction cases, the mechanism of structural damages and the principle of vortex shedding were studied. Using FLUENT software, stability change of flow over a backward-facing step were calculated and streamline pattern were drawn under the condition of without external excitation and blowing in the wall while sucking independently when Re=1000. Furthermore, the result compared with that of Lambros Kaiktsis et al (2003).
