A Survey of Wind and Turbulence Modeling Methods.
Abstract
The purpose of this survey was to determine the type of work being done in the field of wind and turbulence modeling as related to the problems encountered in the use of free-flight flat-fire rockets in the atmospheric boundary layer. In addition, it was desired that the modeling techniques which seemed particularly relevant be explained from an applied engineering point of view. The first section of this report contains a summary of surveys of the available literature relevant to modeling low level winds. The second section to this report consists of a summary of meetings and phone contacts between Control Dynamics and various authorities in the fields of atmospheric science. Section 3 consists of definitions of some commonly encountered terms used to describe the assumptions used in modeling turbulence. Sections 5 through 8 consist of discussions of specific work which appears relevant to the modeling of wind with regard to rocketry problems. These topics include the approximation of the von Karman turbulence spectra with a rational function, effects of atmospheric stability on turbulence, data available on mean winds and standard deviations, and the spatial modeling of wind and turbulence.
