Two-degree-of-freedom subsonic wing rock and nonlinear aerodynamic interference
… configurations employing close-coupled canards, such as the X-29, comes the need to simulate unsteady aerodynamic interference. A versatile method based on the general unsteady vortex-lattice technique has been developed. The method yields the time histories of the pressure distribution …

Development and application of an integrated aerodynamic and thermodynamic testing system for cars
… angularity of a device, such as the side front canards, to the flow direction, can significantly alter its function. The flow visualization test showed that the local flow direction strongly depends on the local geometry. The temperature study revealed that the underbody cooling was jeopardized …

Rate-induced tipping to metastable Zombie fires
Surface wildfires are generally believed to be the cause of so-called Zombie fires observed in peatlands, that disappear from the surface, smoulder underground during the winter, and ''come back to life" in the spring. Here, we propose rate-induced tipping (R-tipping) to a subsurface hot metastable …

On the interaction of rate-induced and bifurcation-induced tipping in ecosystems
We analyse nonlinear tipping phenomena in a bi-stable ecosystem model, defined as sudden and unexpected transitions from the herbivore-dominating equilibrium to the plant-only equilibrium, which are triggered by environmental changes represented by time-varying parameters [Scheffer et al. {\em …
