GLOBAL INSTABILITIES IN SPATIALLY DEVELOPING FLOWS: Non-Normality and Nonlinearity (2005, methodology): “Figure 1 presents an example of the self-sustained oscillations occurring in the separated boundary layer flow over a double-bump topography as computed by Marquillie & Ehrenstein (2003).”
Optimal growth, model reduction and control in a separated boundary-layer flow using global eigenmodes (2007, methodology): “By confining the recirculation bubble between two successive bumps on the plate, Marquillie & Ehrenstein (2003) interpreted the flow oscillations in terms of the existence of a global saturated mode oscillating with a well-defined period.”
On two-dimensional temporal modes in spatially evolving open flows: the flat-plate boundary layer (2005, methodology): “The underlying algorithm has been described in Marquillie & Ehrenstein (2003).”
Stability and receptivity characteristics of a laminar separation bubble on an aerofoil (2010, background): “…been observed for analytically constructed velocity profiles (Hammond & Redekopp 1998) and artificially generated separation bubble flows (Hammond & Redekopp 1998; Marquillie & Ehrenstein 2003), it has not yet been detected for separation bubbles naturally occurring on an aerofoil or flat plate.”
