Large-scale motions and self-similar structures in compressible turbulent channel flows
Cheng Cheng, Lin Fu
In this work, we study the scale characteristics of the log- and outer-region motions and structures in subsonic and supersonic turbulence. To this end, a series of direct numerica…
Streamwise inclination angle of wall-attached eddies in turbulent channel flows
Cheng Cheng, Wei Shyy, Lin Fu
We develop a new methodology to assess the streamwise inclination angles (SIAs) of the wall-attached eddies populating the logarithmic region with a given wall-normal height. To re…
A six-point neuron-based ENO (NENO6) scheme for compressible fluid dynamics
Yue Li, Lin Fu, Nikolaus A. Adams
In this work, we introduce a deep artificial neural network (ANN) that can detect locations of discontinuity and build a six-point ENO-type scheme based on a set of smooth and disc…
A Block-based Adaptive Particle Refinement SPH Method for Fluid-Structure Interaction Problems
Tianrun Gao, Huihe Qiu, Lin Fu
The multi-resolution method, e.g., the Adaptive Particle Refinement (APR) method, has been developed to increase the local particle resolution and therefore the solution quality wi…
Consistency between the attached-eddy model and the inner-outer interaction model: a study of streamwise wall-shear stress fluctuations in a turbulent channel flow
Cheng Cheng, Lin Fu
The inner-outer interaction model (Marusic, Mathis & Hutchins, Science, vol. 329, 2010, 193-196) and the attached-eddy model (Townsend, Cambridge University Press, 1976) are two fu…
Compressible Velocity Transformations for Various Noncanonical Wall-Bounded Turbulent Flows
Tianyi Bai, Kevin P. Griffin, Lin Fu
This work assesses several popular transformations for the velocity profile through their application to several types of non-canonical compressible wall-bounded turbulent flows. S…
