“…One-dimensional anti-icing analyses using LewINT® ice accretion software have been reported to provide satisfactory results for heat flux estimations [30,38]. The composition of the blade sections and the material thermal properties are as pre-defined in LewINT® [14]. It is assumed that the anti-icing will be operated in a running-wet state.…”

“…Despite Electrothermal anti-icing [6,[13][14][15][16][17] and derating [18][19][20] being actively researched for ice mitigation, 4 to the authors' knowledge, no method has been developed to compare them and the following research questions remain unknown and need to be answered:…”

“…Further research on anti-icing systems has focused on evaluating electrothermal anti-icing system power requirements during an icing event without accounting for post-icing event losses [13,14,28], which results in under predicted ice-induced losses. Thus, there is a need to investigate the performance of electrothermal anti-icing techniques when considering icing losses both during and after icing events, whilst also accounting for a system's financial viability.…”

“…In another work (Buschhorn et al 2013), the application of conductive polymer nanocomposites in making highly efficient electro-thermal IPS was tested under a range of icing conditions. In (Reid et al 2013a(Reid et al , 2013b, numerical approaches to performance degradation analysis and to provide guidelines for the design of wind turbine electro-thermal anti-icing systems, are presented. Clean Sky, an aeronautical research program in Europe, has recently launched a project on the combination of smart coatings with electro-thermal systems to minimize the runback ice over natural laminar flow wings' surfaces.…”

Constrained problem formulations for power optimization of aircraft electro-thermal anti-icing systems

et al. 2015

Various constrained problem formulations for the optimization of an electro-thermal wing anti-icing system in both running-wet and evaporative regimes are presented. The numerical simulation of the system is performed by solving the conjugate heat transfer problem between the fluid and solid domains. The optimization goal is to reduce the energy use and power demand of the anti-icing system while ensuring a safe protection. The formulations are carefully proposed from the physical and mathematical viewpoints; their performance is assessed by means of several numerical test cases to discern the most promising for each regime. The design optimization is conducted using the mesh adaptive direct search algorithm using quadratic and statistical surrogate models in the search step. The influence of the models on the convergence speed and the quality of the obtained design solutions is investigated.

“…When the local temperature is near the freezing point, only a fraction of the water droplets freezes upon impact with an exposed surface. The remaining water is free to run back and freeze downstream, driven by shear stresses, gravity and in the case of wind turbines, rotational forces [9]. Ice accretion can degrade the aerodynamic characteristics of a rotating wind turbine rotor [10,11].…”

A numerical study is presented in this paper to investigate blade sections (NACA 4415) with a scaling analysis. For variable rotational speeds (up to 60 RPMs) and operating/icing conditions for both similar models, the effects on the flow field, droplet impingement and ice accretion process are obtained. The numerical simulations are conducted using ANSYS FENSAP ICE software. Effects of the relative flow Reynolds number and speed ratio over two similar blade sections are investigated. Flow velocity contours, pressure distributions, droplet impingement/collection efficiencies and ice shapes/quantities are presented. The results of this paper provide useful insight to predict icing on wind turbine blades including scaling effects among different blade configurations.
