Dependence of Strehl ratio on turbulence model

摘要

Propagation of electro-optical signals through the boundary and coolant mixing layers on a hypervelocity vehicle can cause severe `aero-optic' signal degradation. This paper examines the use of approximate turbulence structure functions and various turbulence models in predicting such signal degradation. Approximate and exact solutions are compared. Characteristics of the Strehl ratio for small and large turbulence scale regimes are discussed.
