    • Droplet distribution spectrum effects on dry ice growth on cylinders 

      Sokolov, Pavlo; Virk, Muhammad (Journal article; Peer reviewed, 2019-01-06)
      A detailed parametric analytical study along with a series of viscid multiphase numerical simulations of ice accretion were performed in comparison with experimental data of ice accretion on a 30 mm diameter cylinder. The study was performed for droplet distribution spectra, Langmuir (A-J), in addition to an experimental droplet distribution obtained in an icing tunnel.<br>Analysis shows that droplet ...

    • Review of Icing Effects on Wind Turbine in Cold Regions 

      Virk, Muhammad; Afzal, Faizan (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-05)
      This paper describes a brief overview of main issues related to atmospheric ice accretion on wind turbines installed in cold climate region. Icing has significant effects on wind turbine performance particularly from aerodynamic and structural integrity perspective, as ice accumulates mainly on the leading edge of the blades that change its aerodynamic profile shape and effects its structural dynamics ...

    • Study of ice accretion and icing effects on aerodynamic characteristics of DU96 wind turbine blade profile 

      Jin, Jia Yi; Virk, Muhammad (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-26)
      In order to optimize the large wind turbines operation in ice prone cold regions, it is important to better understand the ice accretion physics and its effects on aerodynamic performance and power production losses. This paper describes a case study of ice accretion on DU96-W-180 airfoil, which has been used for large wind turbine blades such as NREL 5 MW. Analysis has been carried out for glaze ...
