High-Reynolds number calculations of turbulent heat transfer in FlowVision software [PDF]
Компьютерные исследования и моделирование, 2018 This work presents the model of heat wall functions FlowVision (WFFV), which allows simulation of nonisothermal flows of fluid and gas near solid surfaces on relatively coarse grids with use of turbulence models.

An algebraic model for prediction of bypass and separation-induced transition in turbomachinery boundary layers [PDF]
, 2016 An algebraic intermittency model for bypass and separation-induced transition is presented. The model modifies the production terms of a k-omega turbulence model. It uses only local variables and is tuned for turbomachinery flows.
