Abstract

Study of transition location effect (from natural transition to fully turbulent) on separation size, shock structure and unsteadiness was the focus of this WP. Boundary layer tripping (by wire or roughness) and flow control devices (VG) were used for boundary layer transition induction. Although this type of flow field had been studied widely in the past, there remains considerable uncertainty on the effects of transition on transonic aerofoil performance. In particular it is not known how close to the shock location transition has to occur to avoid detrimental effects associated with laminar shock-induced separation. Furthermore, it was unclear how best to provoke transition on an airfoil featuring significant laminar flow and how close to the shock this needs to be performed. Finally, current CFD methods are particularly challenged by such transitional flows. In this work package some of the findings from the basic research performed in other WPs was applied. Specialized large-scale transonic wind tunnels running cost is very high therefore using such facilities is not appropriate for upstream research programs such as TFAST. Therefore we have used existing wind tunnels within our consortium. One of these is a transonic test section at UCAM where laminar and transitional profiles were studied previously at Reynolds numbers up to 2 million (based on chord length). This wind tunnel allowed basic investigations of the transition location effects on a shock induced separation and unsteadiness for a relatively large number of parameters. A larger wind tunnel at Institute of Aviation in Warsaw was used, which enabled the investigation of a much larger aspect ratio profile. In this facility it was possible to measure a whole force polar up to and including the buffet boundary. The research was carried out for the natural b/l transition location as well as different methods of tripping.

Notes

  1. 1.

    Zero incidence buffet has been observed by previous investigators both experimentally and numerically, predominantly in research on thick biconvex aerofoils in small wind tunnels. Lee [28], Mabey [29] in particular came to the same conclusion as here that for thickness-to-chord ratios greater than 12% the buffet boundary at Rec = 0.6 × 106 (as detected by a wall-mounted pressure transducer) had little dependence on transition (though at very low Reynolds numbers the untripped flow began buffeting at a lower Mach number, with higher pressure fluctuations). No buffet was observed when the aerofoil was given an angle of attack, due to increased confinement effects.
