Accuracy analysis and optimization of scale-independent third-order WENO-Z scheme with critical-point accuracy preservation
Yunchuan Wu, Xiuzheng Cheng, Yi Duan +4
To address the order degradation at critical points in the WENO3-Z scheme, some improvements have been proposed , but these approaches generally fail to consider the occurrence of…

Evolution and sudden change of steady interactions of low enthalpy hypersonic double wedge flows with fore angle
Yihui Weng, Yi Duan, Qin Li +4
The evolution and sudden change of steady interaction structures is numerically studied with the fore wedge angle theta_1 in a low enthalpy hypersonic double wedge configuration. I…

Design of a variable-Mach-number waverider by the osculating-curved-cone method using a rational distribution function and incorporating the equilibrium-gas model
Mengyu Wang, Yi Duan, Qin Li +2
When a waverider flies at hypersonic speed, the thermodynamic properties of the surrounding gas change because of the rapid increase in temperature, so it is reasonable to consider…
