1. 1. Turbine-Mounted Lidar:The pulsed lidar as a reliable alternative.

   University essay from Institutionen för kultur, energi och miljö

   Author : Isaac Braña; [2011]
   Keywords : Wind power; doppler lidar; pulsed lidar; continuous-wave lidar; power control system; wind turbine-mounted lidar.;

   Abstract : Expectations for turbine-mounted lidar are increasing. The installation of lidars in wind turbine nacelles for measuring incoming winds, preventing wind gusts and increasing energy productions is after recently studies, technically and economically feasible. READ MORE

3. 2. Validation of software for the calculation of aerodynamic coefficients : with a focus on the software package Tornado

   University essay from Fluid och mekanisk systemteknik

   Author : Ramón López Pereira; [2010]
   Keywords : Aerodynamic coefficients; Aerodynamiska koefficienter;

   Abstract : Several programs exist today for calculating aerodynamic coefficients that with some simplifications provide fast approximations of the values for a real aircraft. Four different programs were analyzed for this report: Tornado, AVL, PANAIR and a handbook-type preliminary method. In addition, ANSYS CFX was used for airfoil validation. READ MORE
