Perturbed spiral real‐time phase‐contrast MR with compressive sensing reconstruction for assessment of flow in children [PDF]
Magnetic Resonance in Medicine, 2019 Purposewe implemented a golden‐angle spiral phase contrast sequence. A commonly used uniform density spiral and a new ‘perturbed’ spiral that produces more incoherent aliases were assessed. The aim was to ascertain whether greater incoherence enabled more accurate Compressive Sensing reconstruction and superior measurement of flow and velocity.MethodsA

Numerical modelling the air flow in parts of air jet loom
Computer Assisted Methods in Engineering and Science, 2023 Paper summarizes the first results of two-dimensional (2D) numerically modelled expansion and flow of compressible and non-viscous gas in typical parts of air jet weaving system; namely in main nozzle designed as an ejector with various shapes of the ...

Compressible two-dimensional turbulence: cascade reversal and sensitivity to imposed magnetic field
New Journal of Physics, 2023 We study the impact of compressibility on two-dimensional turbulent flows, such as those modeling astrophysical disks. We demonstrate that the direction of cascade undergoes continuous transition as the Mach number Ma increases, from inverse at Ma = 0 ...

Real Gas Models in Coupled Algorithms Numerical Recipes and Thermophysical Relations
International Journal of Turbomachinery, Propulsion and Power, 2020 In the majority of compressible flow CFD simulations, the standard ideal gas state equation is accurate enough. However, there is a range of applications where the deviations from the ideal gas behaviour is significant enough that performance predictions

Achieving acoustic cloak by using compressible background flow
, 2016 We propose a scheme of acoustic spherical cloaking by means of background irrotational flow in compressible fluid. The background flow forms a virtual curved spacetime and guides the sound waves bypass the cloaked objects.
