In order to determine the appropriate spacing between wind turbines, a research program was initiated to characterize the recovery of the wake behind a large wind turbine. The research program had two aspects. The first was the development of an analytical model of wake recovery downwind of the turbine. The analytical model was developed to calculate the wake properties as functions of the downwind coordinate and to generate wind speed profiles (i.e., wind speed as a function of the lateral coordinate for selected altitudes and wind speed as a function of the vertical coordinate) at selected distances downwind of the turbine. The inputs to the model included wind speed, ambient turbulence, and turbine geometric parameters. The second aspect of the program was an experimental program to measure the wake behind the Mod-0A wind turbine at Clayton, New Mexico. The Lockheed laser Doppler velocimeter was used to make the measurements. This volume contains a description of the analytical model development.
