Predicting trigger in streak breakdown via Picard-Chebyshev approach in plane-Poiseuille flow
Nobutaka Taniguchi, Aiko Yakeno
The evolution of finite-amplitude disturbances is critical in the prediction of laminar-to-turbulent transition. To analyze the transient growth of disturbances, Pralits et al. (J.…
DMR effect on drag reduction of a streamlined body measured by Magnetic Suspension and Balance System
Aiko Yakeno, Hiroyuki Okuizumi, Kento Inokuma +1
This study experimentally investigates the aerodynamic drag reduction capabilities of distributed micro-roughness (DMR) coatings on a streamlined model, utilising the 1-m magnetic…
Combined thermographic measurement and heat-flux compensation methods for aerodynamic heating evaluation in hypersonic flight
Kento Inokuma, Aiko Yakeno, Yoshiyuki Watanabe +1
Novel thermographic measurement and heat-flux compensation methods combined for evaluating aerodynamic heating in hypersonic flight were developed using high-speed thermography. A…
Minimal seed in supersonic boundary layer at
Nobutaka Taniguchi, Aiko Yakeno
This study investigates the minimal seed for laminar-to-turbulent transition in a supersonic boundary layer at and using adjoint-based nonlinear non-modal analysis…
