Measurements of Air Entrainment by Bow Waves [PDF]
Journal of Fluids Engineering, 2000 This paper describes measurements of the air entrained in experiments simulating the breaking bow wave of a ship for Froude numbers between two and three. The experiments and the characteristics of the wave itself are detailed in T. Waniewski, 1999, “Air Entrainment by Bow Waves; Ph.D. theses, Calif. Inst.

Airfoil leading edge blowing to control bow shock waves [PDF]
Scientific Reports, 2020 AbstractThis manuscript presents a detailed characterization of active control of bow shock waves via leading edge injection, including subsonic coolant ejection and the appearance of Coanda effects. The flow phenomena occurring at steady and pulsating flow injection regimes were analyzed using steady and unsteady two-dimensional Reynolds-Averaged ...

Design and Principles Analysis of Hydrofoil Appendages for Reducing Resistance of High-Speed Ships
Journal of Marine Science and EngineeringTo reduce the resistance of high-speed displacement ships with Froude numbers (Fr) between 0.4 and 0.5, this paper proposes the installation of hydrofoils at the bow and stern of the ship.

Competing orders and unconventional criticality in the Su-Schrieffer-Heeger model
Physical Review Research, 2020 The phase diagram of the one-dimensional Su-Schrieffer-Heeger model of spinless fermions coupled to quantum phonons is determined by quantum Monte Carlo simulations and differs significantly from previous work.

Void Fraction Measurment Beneath a Stationary Breaking Wave [PDF]
, 1998 Impedance based techniques have been used to quantify air entrainment by a stationary breaking wave at the bow of a ship. The present paper describes an impedance based void fraction meter which was developed to make measurements in this high speed ...

Mechanism of stimulated Hawking radiation in a laboratory Bose-Einstein condensate
, 2017 We model a sonic black hole analog in a quasi one-dimensional Bose-Einstein condensate, using a Gross-Pitaevskii equation matching the configuration of a recent experiment by Steinhauer [Nat. Phys. 10, 864 (2014)].
