Shock-structure effect on its stability – S2T Unit

The Okinawa Institute of Science and Technology Graduate University (OIST; see is a dynamic new graduate university of science and technology in Okinawa Prefecture, Japan. The university is located on 85 hectares of protected forestland overlooking beautiful shoreline and coral reefs. The campus is striking architecturally, and the facilities are outstanding (OIST campus video tour). There are no academic departments, which facilitates multidisciplinary research. Outstanding resources and equipment are provided and managed to encourage easy access and collaboration. English is the official language of the University, and the university research community is fully international, with more than 50 countries represented. OIST is rapidly gaining recognition in the worldwide academic community as a model for excellence in education and research.


Position summary:

The Shocks, Solitons & Turbulence (S2T) Unit (lead by Emile Touber) is looking for a postdoctoral scholar to study the stability of shock waves using mathematical and computational techniques borrowed from incompressible flows (e.g. resolvent). In particular, we want to understand how the structure of the shock governs the response of the front to both small- and large-amplitude perturbations. The shock structures of interest to us will be associated with out-of-equilibrium phenomena and non-ideal fluids. The transition from/to weak to/from strong shocks is of particular interest (e.g. is it associated with a supercritical bifurcation?), as well as sound- and shear-wave emissions from composite waves in non-ideal fluids (see Touber & Alferez). Applications range from external aerodynamics (entry vehicle), propulsion (rocket engines) to energy production (supercritical cycles, fusion).
