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…
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…
Shear-induced droplet mobility within porous surfaces
Si Suo, Haibo Zhao, Shervin Bagheri +2
Droplet mobility under shear flows is important in a wide range of engineering applications, e.g., fog collection, and self-cleaning surfaces. For structured surfaces to achieve su…
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…
Numerical Study of Viscoelastic Upstream Instability
Sai Peng, Tingting Tang, Jianhui Li +2
In this work, we report numerical results on the flow instability and bifurcation of a viscoelastic fluid in the upstream region of a confined cylinder in a narrow channel. Two-dim…
Isogeometric analysis with local adaptivity based on a posterior error estimation for elastodynamics
Peng Yu, Cosmin Anitescu, Satyendra Tomar +2
This paper presents a novel methodology of local adaptivity for the frequency-domain analysis of the vibrations of Reissner-Mindlin plates. The adaptive discretization is based on…
