Transonic dislocation propagation in diamond [PDF]
Science, 2023 The motion of line defects (dislocations) has been studied for more than 60 years, but the maximum speed at which they can move is unresolved. Recent models and atomistic simulations predict the existence of a limiting velocity of dislocation motion ...

Drag reduction on a transonic airfoil [PDF]
Journal of Fluid Mechanics, 2022 Flow control for turbulent skin-friction drag reduction is applied to a transonic airfoil to improve its aerodynamic performance. The study is based on direct numerical simulations (with up to 1.8 billion cells) of the compressible turbulent flow around ...

Importance of Air Humidity and Contaminations in the Internal and External Transonic Flows
Energies, 2020 The paper presents mathematical modelling of steam condensation in the atmospheric air transonic flows. A single-fluid model was employed. The model was validated against the in-house experimental studies of internal flow in nozzles and against benchmark

Learning Neural-Network-Based Turbulence Models for External Transonic Flows Using Ensemble Kalman Method [PDF]
AIAA Journal, 2023 This paper presents a neural-network-based turbulence modeling approach for transonic flows based on the ensemble Kalman method. The approach adopts a tensor-basis neural network for the Reynolds-stress representation, with modified inputs to consider ...

Connecting transonic buffet with incompressible low-frequency oscillations on aerofoils [PDF]
Journal of Fluid Mechanics, 2023 Self-sustained, low-frequency, coherent flow unsteadiness over rigid, stationary aerofoils in the transonic regime is referred to as transonic buffet. This study examines the role of shock waves in sustaining this transonic phenomenon and its relation to

On some smooth symmetric transonic flows with nonzero angular velocity and vorticity [PDF]
Mathematical Models and Methods in Applied Sciences, 2021 This paper concerns the structural stability of smooth cylindrically symmetric transonic flows in a concentric cylinder. Both cylindrical and axi-symmetric perturbations are considered.
