    • 3D CFD modeling of air flow through a porous fence 

      Xu, Yizhong; Mustafa, Mohamed Y.; Knight, Jason; Virk, Muhammad; Haritos, George (IEEE Computer Society, 2013)
      Numerical simulation has played an important role in systematic study on the performance of porous fences over the last three decades. In this paper, a 3D CFD model to simulate air flow through a porous fence is presented. ...

    • Delamination threshold load of composite laminate under low-velocity impact 

      Xu, Yigeng; Shen, Zeng; Tiu, William; Xu, Yizhong; Chen, Yong; Haritos, George (2013)
      A key factor affecting the use of carbon fibre reinforced composite laminates is the low velocity impact damage which may be introduced accidentally during manufacture, operation or maintenance of the component. Among the ...

    • Factors Influencing the Performance of Porous Wind Shields 

      Xu, Yizhong; Virk, Muhammad S.; Knight, Jason; Mustafa, Mohamad Y.; Haritos, George (TRANS TECH PUBLICATIONS LTD, 2013)
      Porosity, porosity distribution, porous shape, porous size, thickness of shield, shield height &width, and shield orientation are the factors that influence the performance of porous wind shields. Among them, porosity is ...

    • Numerical simulation of crack tip behaviour under fatigue loading 

      Xu, Yigeng; Tiu, William; Xu, Yizhong (2013)
      Fatigue damage is a localized phenomenon controlled by the near-tip crack behavior. This paper presents an application of a dislocation distribution technique to the simulation of crack tip behavior under fatigue loading. ...

    • Wind Shielding Analysis for Cold Regions Using Experimental and Numerical Techniques 

      Xu, Yizhong (2016-08-16)
      The thesis presents a systematic experimental and numerical study on the interactions among porous fence, airflow, and windblown snowdrifts, a knowledge that will contribute to optimize the performance of porous wind ...
