V2F Module


Predictions of heat transfer in rib-roughened channels using the V2F module

The V2F is a Reynolds-Averaged Navier-Stokes (RANS) closure developed to accurately capture the turbulence anisotropy near solid wall, and therefore provides superior predictions of flow separation, viscous drag and heat transfer. The model is an extension of the classical k-e model, obtained by including transport equations for quantities representative of the Reynolds stress anisotropy induced by wall blockage. In spite of its increased complexity with respect to the original k-e model, the V2F model is numerically stable and reproduces important characteristics of the Reynolds stress transport models without introducing computational difficulties. The V2F model has been applied to a wide variety of problems and is currently used by hundreds of universities and industries. The model has been implemented in several in-house and commercial codes (Ansys CFX, Adapco Star-CD) and is currently available as an add-on for Ansys Fluent.
