The process of primary vortices forming,lifting and shedding alternately along central axis from opposite sides of a slender body placed at high incidence to an oncoming stream is investigated numerically,and laws on axial evolution of its sectional flow-pattern topological structure are advanced.
运用数值方法研究了细长体大攻角绕流背风面两侧主涡沿轴向交替形成、飘起、脱落的过程,提出了绕流截面流态拓扑结构的轴向演化规律,详细描述了主涡诱导产生二次涡、二次涡分割主涡衍生出tertiary涡、主涡与异侧二次涡绕合、主涡分割异侧主涡形成脱体涡等现象,突出了二次涡、tertiary涡的作用。
