New routes to the synthesis of various novel chiral maleimides are described. The oxabicyclic anhydride 2 readily available exo-Diels-Alder adduct of furan and maleic anhydride was used as a vehicle, which in turn reacted with hydrochlorides of amino

Knowledge on the boundary-layer transition location at large chord Reynolds numbers (Re ≥ 3 million) is essential to evaluate the performance of airfoils designed for modern wind-turbine rotor blades, which rotor diameters can be of the order of hu

For aerodynamic profile tests on aircraft models, boundary-layer transition detection is of great interest. Under ambient flow conditions the infrared technique (IR) is a well-established image-based method for this purpose. In high Reynolds number t

The influence of the streamwise pressure gradient and a nonadiabatic surface on boundary layer transition was experimentally investigated at the Cryogenic Ludwieg-Tube Gottingen, Germany. Boundary layer transition was detected nonintrusively by means
