“…FENSAP‐ICE has not been validated for use on wind turbines, but it has been validated extensively for ice accretion on streamlined bodies like aircraft wing profiles (airfoils) at high Reynolds numbers, similar to the range of Reynolds numbers for the wind turbine blade profiles used for this study. The ice shapes formed are small, and only rime ice is investigated, so this is not deemed to introduce a large inaccuracy.…”

A numerical study of power performance losses due to ice accretion on a large horizontal axis wind turbine blade has been carried out using computational fluid dynamics (CFD) and blade element momentum (BEM) calculations for rime ice conditions. The computed aerodynamic coefficients for the normal and iced blades from the CFD calculations were used together with the BEM method to calculate the torque, power and C p curves of the wind turbine for both normal and icing conditions. The results are compared with the published data. It is shown that icing results in a reduced power production from the turbine and that changing the turbine controller could improve the power production with iced blades. Copyright

“…Research on icing of airfoils and the resulting degradation has been ongoing in the aviation industries since the 1920s . 2D and 3D ice accretion simulation tools have been developed such as lewice , fensap‐ice and turbice . Estimation of changes in geometry and in surface roughness due to icing are two main objectives of these codes.…”

This article deals with the atmospheric ice accumulation on wind turbine blades and its effect on the aerodynamic performance and structural response. The role of eight atmospheric and system parameters on the ice accretion profiles was estimated using the 2D ice accumulation software LEWICE Twenty-four hours of icing, with time varying wind speed and atmospheric icing conditions, was simulated on a rotor. Computational fluid dynamics code, FLUENT, was used to estimate the aerodynamic coefficients of the blade after icing. The results were also validated against wind tunnel measurements performed at LM Wind Power using a NACA64618 airfoil. The effects of changes in geometry and surface roughness are considered in the simulation. A blade element momentum code WT-Perf is then used to quantify the degradation in performance curves. The dynamic responses of the wind turbine under normal and iced conditions were simulated with the wind turbine aeroelastic code HAWC2. The results show different behaviors below and above rated wind speeds. In below rated wind speed, for a 5 MW virtual NREL wind turbine, power loss up to 35% is observed, and the rated power is shifted from wind speed of 11 to 19 m s À1 . However, the thrust of the iced rotor in below rated wind speed is smaller than the clean rotor up to 14%, but after rated wind speed, it is up to 40% bigger than the clean rotor. Finally, it is briefly indicated how the results of this paper can be used for condition monitoring and ice detection.

“…Extension to particle flows in airways was more recently attempted [6,8]. The Eulerian droplet model has been studied by several authors at the numerical level [7] and at the practical level [2,6,8,9,25,38]. To our knowledge, there is no theoretical study related to the system of zero-pressure gas dynamics including explicitly a right-hand side term as in (1.1).…”

We study an Eulerian droplet model which can be seen as the pressureless gas system with a source term, a subsystem of this model and the inviscid Burgers equation with source term. The condition for loss of regularity of a solution to Burgers equation with source term is established. The same condition applies to the Eulerian droplet model and its subsystem. The Riemann problem for the Eulerian droplet model is constructively solved by going through the solution of the Riemann problems for the inviscid Burgers equation with a source term and the subsystem, respectively. Under suitable generalized Rankine-Hugoniot relations and entropy condition, the existence of delta-shock solution is established. The existence of a solution to the generalized Rankine-Hugoniot conditions is proven. Some numerical illustrations are presented.
