A Preconditioned Method for Rotating Flows at Arbitrary Mach Number
Modelling and Simulation in Engineering, 2011 An improved preconditioning is proposed for viscous flow computations in rotating and nonrotating frames at arbitrary Mach numbers. The key to the current method is the use of both free stream Mach number and rotating Mach number to construct a ...

Measuring the Alfvenic Nature of the Interstellar Medium: Velocity Anisotropy Revisited
, 2014 The dynamics of the interstellar medium (ISM) are strongly affected by turbulence, which shows increased anisotropy in the presence of a magnetic field. We expand upon the Esquivel & Lazarian method to estimate the Alfven Mach number using the structure ...

Incoherent Digital Holography Empowered by Wavefront and Information Engineering: A Review
Advanced Photonics Research, EarlyView.Advancements in incoherent digital holography (IDH) have been achieved via wavefront engineering (using spatial light modulators, diffractive optics, and metasurfaces) and information engineering (using compressive sensing and deep learning). This paper presents an overview of IDH with wavefront and information engineering, paving the way toward its ...

Ultralow Loss Coupling Tuning of Photonic Accelerators
Advanced Photonics Research, EarlyView.A polymer material cured by electron beam is used to perform precise and ultralow loss tuning on photonic accelerators made for highly efficient computation. The versatility of the technique is demonstrated on a large number of directional coupler devices with varying initial coupling ratios and application on a crossbar array for matrix multiplication

Note on the limits to the local Mach number on an aerofoil in subsonic flow [PDF]
, 1948 It has been noted in some experiments that the local Mach number just ahead of a shock wave on an aerofoil in subsonic flow is limited, values of the limit of the order of 1.4 are usually quoted.
