| Description: |
Actual fundamental and computational problems of laminar–turbulent transition prediction in aerodynamic flows are discussed. The author’s approach based on the exp(N)-method is briefly described. The results of experimental studies aimed at clarifying the calibration of the exp(N)-method is highlighted. Particularly, one of the main problem is a limited experimental database for verification of different approaches for the transition prediction. To extend such a database, it is necessary to document in detail the flow parameters (velocity, free-stream turbulence level, etc.) and the model parameters (geometry, surface roughness, angle of attack, etc.) as well as to document in a statistically sound way the position of laminar-turbulent transition on the surface of experimental model. To this end we develop an experimental method of parametric measurements in different flow regimes of three-dimensional aerodynamic flows based on the thermal analysis of the surface. |
