Israeli work on aerogenerator shrouds.

Research output: Contribution to journalArticlepeer-review

Abstract

Ben Gurion Univ. of the Negev, Israel Past work in Israel has shown that wind turbines enclosed in specially designed shrouds can increase the output of power of the turbine by a factor of 3 or so, as compared with unshrouded turbines under the same free wind stream conditions. However, first generation shrouds were found to be unacceptable for economical use, i.e., the ratio of the shroud's total length to throat diameter was of the order of 7. The main purpose of the present work was to arrive at a compact shroud configuration, without sacrificing aerodynamic performance. The results clearly indicate that it is possible to obtain shrouds with a total length to throat diameter ratio that is smaller than 3, and that have an aerodynamic performance similar to the first-generation model.
