... paper, the DWM model is presented in a version suitable for full integration in an aeroelastic model. Calibration and validation of the different parts of the model is carried out by comparisons with actuator disk and actuator line (ACL) computations as well as with inflow measurements on a full-scale 2...

...S. C. McIntosh; H. Babinsky; T. Bertényi The application of actuator-disk momentum models to highly loaded vertical axis rotors (large tip speed ratios/solidities) frequently results in a convergence failure of the iterative method employed and the production of nonphysical erratic solutions...

... of the trailing edge geometry was, in all the considered cases, small enough to justify the use of a potential flow code for calculation of the aerodynamic forces. Calculations showed that the effect of a time lag in the actuators and sensors may drastically reduce the efficiency of the control algorithm...

...Wen Zhong Shen; Jens Nørkær Sørensen; Robert Mikkelsen A new tip loss correction, initially developed for 1D Blade Element/Momentum (BEM) computations (submitted to Wind Energy), is now extended to 2D Actuator Disc/Navier–Stokes (AD/NS) computations and 3D Actuator Line/Navier–Stokes (AL/NS...

...George M. Lloyd; Kwang J. Kim; A. Razani; Mohsen Shahinpoor Metal hydrides have been investigated for use in a number of solar thermal energy applications, such as heat regenerators or hydrogen storage technology, but rarely for thermal actuators. Preliminary experimental results from a prototype...
