Hot wire visualization of breakdown to turbulence in complex flows Chernoray, V.G., Kozlov, V.V., Löfdahl, L., Pratt, P.R. 2006 Thermophysics and Aeromechanics 13 (2), 213–220, MAIK Nauka/Interperiodica Publishing The nonlinear stage of breakdown to turbulence is a strongly three-dimensional process and represents a difficult task for experimental studies. Investigation of laminar-turbulent transition in aerospace applications additionally involves a complex base-flow with pressure gradients and secondary velocity components resulting in successive increase of necessary measurements. The developed hot-wire visualization technique offers a possibility for an advanced analysis whilst retaining the advantages of traditional visualization methods and is especially suitable for resolving such complex flows.   check pdf
