description: The work is devoted to the introduction into the SINF/Flag-S software package of the possibility of calculating fully developed flows with stabilized heat transfer under the condition of a given heat flux on the walls and the implementation of the WALE subgrid model of the LES method with subsequent cross-verification calculations. The calculations were performed using the finite-volume âunstructuredâ SINF/Flag-S program code and the commercial code ANSYS Fluent on a number of problems with internal, spatially periodic laminar and turbulent flow. Using the version of the code extended by the author, cross-verification calculations were carried out on the problem of fully developed flow and heat transfer in straight pipes of various cross-sections and in a twisted pipe of an oval cross-section, which showed good agreement between the results of SINF/Flag-S and ANSYS Fluent. For the implemented WALE model, subgrid viscosity calculations were performed on an analytically specified velocity field, which showed the correctness of the software implementation. The calibration of the model constant was carried out on the problem of the degeneration of homogeneous isotropic turbulence. Using two codes, comparative calculations of the turbulent outflow of submerged jets into the space between two parallel walls from a series of square-section holes located periodically were performed.
