Readeveloping Turbulent Boundary Layer after Separation-Reattachment(I)
박리-재부착 이후의 재발달 난류경계층 I
- Published : 1989.07.01
Abstract
An experimental study has been performed to investigate the process from nonequilibrium state to equilibrium state in redeveloping turbulent boundary layer beyond separation-reattachment using pitot tube and hot-wire anemometer. The model sued in the experiment has the form of a backward facing step which is assembled by a two-dimensional 4:1 half elipse and a plate. Measurements are carried out up to a distance of about 50 step height downstream of the step, where the reattachment observed at about x/h=6.5. The profiles of the shape factor H the Clauser parameter G and the coefficient of friction
본 연구에서는 재부착 이후의 재발달 난류경계층에서의 난류구조와 비평형 상태에서 평형상태로의 변화 과정을 실험적으로 고찰하고자 한다.
