Dr Xinjun Cui BEng Hons, MSc, PhD, FHEA, MIET

Course Leader for BEng/MEng Aerospace Engineering

Summary

Xinjun is a Senior Lecturer at the Department of Engineering and Maths and the Course Leader for BEng/MEng Aerospace Engineering. He obtained his BEng (1986) and MSc (1989) degrees in Aerospace Engineering in China, and became an academic after his graduation. Between 1999 and 2002, Xinjun did a PhD in Applied Maths funded by EPSRC at Manchester University, entitled "Numerical Computations of the Navier-Stokes equations for confined rotating flows". During his Postdoctoral years, Xinjun worked on various projects funded by EPSRC, NERC and Rolls-Royce at Manchester University and Nottingham University.

  • About

    Xinjun started his teaching and research career in the field of aerospace/mechanical engineering and applied mathematics. In 2008, he joined the University of Wales Newport (now the University of South Wales) as a Senior Lecturer. He later on became a programme leader for the undergraduate engineering provision and was acting as the Head of Engineering during his last year at Newport.

    In 2012, Xinjun joined Sheffield Hallam University for its Aerospace Engineering. He took over the course leadership for the BEng/MEng Aerospace Engineering in 2013. As a result of his diligence and hard work, Xinjun won the University Inspirational Teaching Award (ITA) in 2014 and the College ITA in 2015. Under his supervision, the MEng Aerospace Engineering course also won a College Award in 2015.

    Xinjun has made more than 20 journal papers and has won two distinctive prizes for Science & Technology Development for his research projects in China. During the years, his research area has expended to aerodynamics, CFD modelling and simulation for transonic flows, multi-phase flows, rotating flows, granular flows and natural hazardous flows, and flight mechanics, trajectory modelling and simulation, signal processing and system recognition, etc.

    Dr Cui is often invited as a peer to review the manuscripts for journals, including Journal of Fluid Mechanics, Physics of Fluids. He also holds an honorary research fellowship at Manchester University and is an external examiner for the engineering provision in Wolverhampton Unversity.

    Specialist Areas of Interest:

    - Computational aerodynamics;
    - Granular free-surface flows;
    - Shock wave capturing.

  • Teaching

  • Research

    One of Xinjun's favourite research interests has been focused on computational aerodynamics, in particular for the shock wave capturing techniques for transonic and supersonic flows. This expertise has been extended successfully to study rapid granular free-surface flows and natural hazardous flows such as snow avalanches and volcanic flows, where he made some ground-breaking contributions in this field.

    After joining Sheffield Hallam, Xinjun started to encourage and supervise more final year students on BEng/MEng Aerospace Engineering courses to investigate aerodynamic behaviours of external/internal airflows around airfoils or vehicles at subsonic, transonic and supersonic regions, where fundamental topics such as lifting line theory, panel method, shock waves, Prandtl-Meyer waves, shock wave - boundary layer interaction, aerodynamic heating etc. can be studied with deeper insights. One of his recent works that was completed along with a MEng student, and is entitled "A theoretical approximation of the shock stand-off distance for the flows around a circular cylinder", is being under the review for a leading journal "Physics of Fluids".

    2009-2010, HEA funding, “Open educational resources (OER) project”
    2006-2008, Rolls-Royce Grant, “Integrated model for Aero-engine bearing chamber flows”
    2004-2006, NERC Postdoc Grant (NER/A/S2003/00439), “Granular flows and applications”
