Comparison of three numerical stabilization techniques of viscoelastic flows: vortex shedding behind a confined cylinder
Sai Peng, Peng Yu
In this study, the OpenFOAM platform, based on the finite volume method, is applied to investigate the two-dimensional viscoelastic flow past a circular cylinder. The FENE-P model,…
Subcritical insability of viscoelastic flow over a circular cylinder: A numerical study
Sai Peng, Jia-yu Li, Xin-hui Si +2
In this paper, we discuss whether the instability of viscoelastic flow around a circular cylinder is subcritical or supercritical by numerical simulation. The Oldroyd-B model is se…
Effect of wall slip on laminar flow past a circular cylinder
Yan-cheng Li, Sai Peng, Taiba Kouser
A numerical study of two-dimensional flow past a confined circular cylinder with slip wall is performed. A dimensionless number, Knudsen number () is used to describe the slip…
Wall-induced translation of a rotating particle in viscoelastic fluid
Sai Peng, Peng Yu
Shear-thinning and viscoelasticity are two non-Newtonian fluid properties widely existing in biological fluids. In this study, we found that the translation motion of a rotating pa…
Simulation of flow induced vibration of a cylinder in an expansion tube
Sai Peng, Qiyu Deng, Lin Zhou +2
In this study, a series of simulations are conducted to investigate the motion of a small cylinder in an expansion tube, focusing on two-dimensional dynamics. These simulations are…
Wake asymmetry weakening in viscoelastic fluids: Numerical discovery and mechanism exploration
Sai Peng, Tao Huang, Taiba Kouser +3
Viscoelasticity weakens the asymmetry of laminar shedding flow behind a blunt body in a free domain. In the present study, this finding is confirmed by four unsteady viscoelastic f…
