Numerical schemes of intensive blast wave propagation in large scale complex enviroments

Baozha yu Chongji
A compressible multiphase flow numerical scheme, induced from the multi- component diffuse interface model with arbitrary number of materials, is established to simulate the interaction between distinct materials under extreme conditions.

Numerical Investigation on Temperature and Flow Characteristics of a Tornado-Like Vortex by using Large-Eddy Simulation

Journal of Applied Fluid Mechanics, 2018
The present work is about numerical simulations of the tornado-like vortex flow generated by our group based on LES techniques which is executed on a three-dimensional computational grid and results have been compared with experimental ones.

Absolute/convective instabilities and the convective Mach number in a compressible mixing layer [PDF]

Two aspects of the stability of a compressible mixing layer: Absolute/Convective instability and the convective Mach number were considered. It was shown that, for Mach numbers less than one, the compressible mixing layer is convectively unstable unless ...

A spectral collocation solution to the compressible stability eigenvalue problem [PDF]

A newly developed spectral compressible linear stability code (SPECLS) (staggered pressure mesh) is presented for analysis of shear flow stability, and applied to high speed boundary layers and free shear flows.

A Three-Dimensional Model of a Spherically Symmetric, Compressible Micropolar Fluid Flow with a Real Gas Equation of State

Symmetry
In this work, we analyze a spherically symmetric 3D flow of a micropolar, viscous, polytropic, and heat-conducting real gas. In particular, we take as a domain the subset of R3 bounded by two concentric spheres that present solid thermoinsulated walls.

Evaluation of Real‐Time Cardiovascular Flow MRI Using Compressed Sensing in a Phantom and in Patients With Valvular Disease or Arrhythmia

Journal of Magnetic Resonance Imaging
BackgroundReal‐time (RT) phase contrast (PC) flow MRI can potentially be used to measure blood flow in arrhythmic patients. Undersampled RT PC has been combined with online compressed sensing (CS) reconstruction (CS RT) enabling clinical use. However, CS RT flow has not been validated in a clinical setting.PurposeEvaluate CS RT in phantom and patients ...
