Two postdoc positions on shock/turbulence interactions – 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 two postdoctoral scholars to study shock/turbulence interactions in plasmas and non-ideal fluids using high-fidelity simulations (DNS). We (see Alferez, Nwobu, Touber) have recently shown using the Linear Interaction Analysis (LIA) that shock-induced energy transfers in non-ideal or ionized fluids offer intricate and exciting pathways to convert entropy fluctuations into acoustic and shear waves. For example, the sound emitted at the shock can in theory be significantly damped whilst mixing be significantly promoted in non-ideal fluids, or vortex rings with different speeds be simultaneously produced in ionized fluids, paving the way for novel flow-control techniques to deliver new propulsion & power systems (supersonic combustion, high-pressure internal combustion engines, quiet aircraft, low-grade heat electricity production, inertial confinement fusion), controlled atmospheric entry (Mars exploration), or new particle-production systems (drug manufacturing). Whilst promising, such results are based on linearized equations. The purpose to the present work is to investigate the feasibility of shaping the post-shock turbulence properties using either the non-idealness of the thermodynamic properties of the fluid (1 position), or its electric conductivity (1 position).
