基于浸入边界法的鱼体自主游动的数值模拟
Numerical investigation of freely self-propelled flexible fish using immersed boundary method
摘要
Abstract
Study on the motion performance of interaction between a swimming or flying creatures and fluid ,usually applied to reveal the biological mechanism of mechanics and movement .A “C” type swim-ming fish as the research object ,a flexible model of freely self-propelled swimming fish is established . This model can reflected truly the interaction among fish movement ,internal force and the external fluid . Using hybrid finite difference/finite element immersed boundary method combined with traditional feed-back force method ,the movement of a swimming fish is simulated .The hydrodynamic performance of start-up and cruise process of a swimming fish is analyzed .The results reveal that the conversion of “C”type and“S”type of fish body can improve the efficiency of the fish swimming ,and the conversion of“C”type and“S” type is mainly affected by structure of fish body and flow field .关键词
