Аннотация

A numerical analysis was conducted on a fully developed turbulent flow in a square duct, two opposite walls of which had been roughened. The calculation was performed with the k model and with the k and ε model coupled to the algebraic stress model developed by Launder & Ying. In this duct, a result hitherto unobserved became apparent: namely, there were four relatively large streamwise vortices. The results of the calculation are compared with the authors' experimental results. A prediction of heat transfer was also performed under conditions of a constant wall-temperature.
