Boundary-layer transition in the age of data: from a comprehensive dataset to fine-grained prediction
Wenhui Chang, Hongyuan Hu, Youcheng Xi +3
The laminar-to-turbulent transition remains a fundamental and enduring challenge in fluid mechanics. Its complexity arises from the intrinsic nonlinearity and extreme sensitivity t…
Numerical simulations of attachment-line boundary layer in hypersonic flow, Part II: the features of three-dimensional turbulent boundary layer
Youcheng Xi, Bowen Yan, Guangwen Yang +1
In this study,we investigate the characteristics of three-dimensional turbulent boundary layers influenced by transverse flow and pressure gradients. Our findings reveal that even…
Numerical simulations of attachment-line boundary layer in hypersonic flow, Part I: roughness-induced subcritical transitions
Youcheng Xi, Bowen Yan, Guangwen Yang +3
The attachment-line boundary layer is critical in hypersonic flows because of its significant impact on heat transfer and aerodynamic performance. In this study, high-fidelity nume…
Receptivity and stability of hypersonic leading-edge sweep flows around a blunt body
Youcheng Xi, Jie Ren, Liang Wang +1
This study performs global stability/receptivity analyses of hypersonic sweep flows around a blunt body with an infinite span. For the first time, we obtain the characteristics of…
The new mode of instability in viscous high-speed boundary layer flows
Jie Ren, Youcheng Xi, Song Fu
The new mode of instability found by Tunney et al. is studied with viscous stability theory in this article. When the high-speed boundary layer is subject to certain values of favo…
