Theoretical and experimental investigation of turbulence induced optical degradation in an axial pipe flow
Abstract
The effects of turbulence induced optical degradation on a laser beam propagating through an axial flow beam duct with a section of the duct uniformly heated were investigated theoretically and experimentally. For the experiments, the far field intensity distributions of the propagating laser were obtained for the wall-gas temperature mismatch up to 50 C and three flow velocities. The experimental results compare well with theoretical predictions.
