WebJul 18, 2016 · This paper describes a study of the self-sustaining process in wall-turbulence based on a second order statistical state dynamics (SSD) model of Couette flow. SSD models with this form are referred to as S3T models and self-sustain turbulence with a mean flow and second order perturbation structure similar to that obtained by DNS. Webmodulation @9#, here the incoherent beam is spatially modu-lated directly by amplitude masks with various modulation periods. By actively seeding spatial noise onto an otherwise uniform incoherent beam, we demonstrate that the induced modulation instability has a maximum growth at a certain preferential perturbation period, leading to formation ...

WebApr 4, 2024 · Jitter radiation is incoherent emission in general (Medvedev 2000). However, in this paper, we suggest that the jitter radiation in our model is coherent. We provide two reasons. First, kinetic turbulence provides a perturbation field to jitter radiation in our scenario, and the jitter radiation can have emission in a small coherent length scale. eastenders word searchWebApr 11, 2024 · The influence of physical factors such as light intensity, dynamic perturbations of scattering medium, and optical depth of scattering medium on network imaging are quantitatively analyzed.
