Before joining the University of Southampton, I studied at Northwestern Polytechnical University (NWPU), Xi’an, China where I received my BSc and MSc degrees. I am fortunate to have the opportunity to study in a multi-cultural research team and to have obtained the financial support from China Scholarship Council (CSC) and Rayleigh studentship of the University of Southampton.
Apart from working full time on the research topic of my PhD, I am collaborating with several colleagues on various other projects. I hope that the technical skills, expertise and capabilities that I am acquiring at the University of Southampton will enable me to perform better in the future career.
During the past two years, I have been involved with demonstration work for several modules within the FEE Faculty. The demonstration work includes both computer and experimental labs. I have trained students to learn how to use CAD and CFD software, and to solve basic engineering problems. I was also involved with the wind tunnel demonstrations of the aeroelasticity module. Furthermore, I have contributed in various roles to the organisation of Summer Schools in the last two years and will continue to do so in the current year.
I participated in the following modules:
The research project investigated the design and analysis of power-law shaped leading edge on hypersonic vehicles. A suite of power law leading edges with different design parameters were chosen as possible candidates for blunting geometries. The aerodynamic and aerothermodynamic properties of these shapes were evaluated, including stagnation heating, shock wave stand-off distance and lift-to-drag ratio. The sensitivity of aforementioned properties to design parameters was investigated. Numerical simulations were carried out for several applications, ranging from two-dimensional hypersonic aerofoils to three-dimensional waveriders.
The topic for my PhD research project is on shape design and optimisation of aerial vehicles. The research work is built around three objectives: a) To investigate the influence that numerical parameters have on the optimisation results for two aerofoil problems in transonic flow and provide guidelines for best practice; b) To develop a robust and rapid framework for wing twist optimisation, which is suitable for industrial use in preliminary phases of the aircraft design; c) To investigate multimodal optimisation problems by employing a strategy that combines gradient-free optimisation with surrogate model and gradient-based optimisation using CFD.
The research project for the Master thesis involved the development of an engineering method for predicting aerodynamic heating on hypersonic vehicles. An improved axisymmetic analog method was proposed and a Fortran code was developed to calculate the shear and pressure forces as well as convective heating rates on the surface of hypersonic flight vehicles. A series of test cases were investigated to verify and validate the robustness and accuracy of the proposed method. You can find more details here.
The individual project of my undergraduate study involved the analysis of numerical iteration methods in hypersonic flow simulation. A family of implicit iterative algorithms in finite volume method were analysed. A comparison was performed with respect to the computational performance of convergence and accuracy. The impact of cell aspect ratio of structured grids on these algorithms was investigated. Numerical simulations were carried out for hypersonic nonequilibrium reacting flows.
On top of the research study, I am keen on doing various outdoor activities and I am a fan of sports, particularly tennis, football and basketball. Living in the UK enables me to watch live matches of Premier League, Champions League and ATP world tour finals. I have developed the hobby of running since I came to Southampton in 2015. To date, I have run for Southampton 10K (April 2016), New Forest Half Marathon (September 2016) and Southampton Half Marathon (April 2017). I also enjoy hiking in the mountains and travelling around to experience different nature, culture and history.
