| Abstract: | Based on its brief introduction on flow asymmetry test results of the slender revolutionary body at high angle of attack, this paper has analyzed such influencing factors upon the flow asymmetry as Re number , turbulence model, installment conditions and so on and further probed into the production mechanism of the flow asymmetry at high angle of attack. This paper highlighted its research conclusion at the last paragraph , which supports the concept that spatial dynamical instability results in flow asymmetry of a slender body at high angle of attack. |
