Abstract:
The second part of the article continues numerical studies of convective and dynamic turbulence fields in the vicinity of a group of extended inclined linear optical sources. This paper studies convective air motions in the vertical configuration of an open-side room of optical systems under external wind effect. The initial and boundary conditions of the boundary value problem being solved are similar to those for the horizontal configuration; the geometric and energy characteristics of the optical sources are analogous; the composition and scope of the study are the same as in the first part. The similarities and differences between the results for both configurations are shown.
