Large-eddy simulation of shock-induced flow separation control using SparkJet concept (2016)
Presentation / Conference Contribution

Large-Eddy Simulation (LES) of shock-wave/boundary layer interactions (SWBLI) with SparkJet control technique is carried out in this paper. The base flow is an oblique shock-wave generated by an 8°wedge impinging onto a spatially-developing Mach 2.3...

Numerical investigation on two streamline-traced busemann inlet-isolators (2016)
Presentation / Conference Contribution

This paper presents a computational fluid dynamics (CFD) study of flow characteristics within three-dimensional Busemann inlet with isolator models. The primary aim of the study was to compare various performances between two streamline-traced inlets... Read More about Numerical investigation on two streamline-traced busemann inlet-isolators.

Multistep simulation for three-dimensional ice accretion on an aircraft wing (2016)
Presentation / Conference Contribution

A simplified icing model combined with Eulerian two-phase flow theory has been proposed and the method was employed for direct simulation of ice accretion occurred on an aircraft wing. An innovative wall boundary condition treatment has been proposed... Read More about Multistep simulation for three-dimensional ice accretion on an aircraft wing.

An improved local remeshing algorithm for moving boundary problems (2016)
Journal Article

© 2016 The Author(s). Three issues are tackled in this study to improve the robustness of local remeshing techniques. Firstly, the local remeshing region (hereafter referred to as ‘hole’) is initialized by removing low-quality elements and then conti...

Large-eddy simulation of a three-dimensional shock-wave/turbulent boundary layer interaction of a single-fin (2015)
Presentation / Conference Contribution

The three-dimension (3D) shock-wave/turbulent boundary layer interaction (SWTBLI) raised from a hypersonic flow passing a single-fin at Mach 5 is investigated i by using LES. The performed LES has demonstrated very good agreements with available expe...

DNS of transitional and turbulent flow simulations (2015)
Presentation / Conference Contribution

An in-house direct numerical simulation (DNS) code SBLI has been developed and used extensively for high-performance computation (HPC) of transitional and turbulent flows, most related to shock/boundary-layer interaction problems. The code has also p... Read More about DNS of transitional and turbulent flow simulations.
