An Enhanced Evolutionary Algorithm with a Surrogate Model (2008)
Yongsheng Lian, Meng-sing Liou, Akira Oyama
Abstract. In this paper we present an enhanced evolutionary algorithm (EA) to solve computationally expensive design optimization problems. In this algorithm we integrate a genetic algorithm (GA)...

Membrane and adaptively-shaped wings for micro air vehicles [electronic resource] / (2003)
ABSTRACT: Micro air vehicles (MAVs), with wing span of 15 cm or less and flight speed around 10 m/s, have many applications in both civilian and military areas. The Reynolds number based on the given...

A Gas-kinetic Scheme for Multimaterial Flows and Its Application in Chemical Reaction (1999)
Y. Lian, Yongsheng Lian, Kun Xu
This paper concerns the extension of the multicomponent gas-kinetic BGK-type scheme [26] to multidimensional chemical reactive flow calculations. In the kinetic model, each component satisfies its...

Computational Aeroelasticity Using a Pressure-Based Solver (1998)
Shyy, Wei, Kamakoti, Ramji, Lian, Yongsheng, Regisford, Sean, Kurdila, Andrew
The fluid-structure interaction problem is studied for two different wing configurations based on moving grid techniques. These configurations demonstrate the interaction between a rigid structure...
