Abstract: 

In the present study, a method of Partial-Averaged Navier-Stokes (PANS) equations, purported to perform variable resolution modeling, is used to predict the heat transfer over a square cylinder in a cross-flow. The PANS closure is based on the RANS SSTk-? model paradigm. The simulations were carried out using an open source software, namely, Open FOAM, at Reynolds number=22000. The open source code and the PANS model are validated against the experimental work reported in the literature and it was observed that both the mean flow properties and turbulent statistics were in good agreement with the experimental results.
Further the capability of the PANS approach in predicting heat transfer in turbulent flow is also studied. An algebraic wall function is used for the near wall treatment of the energy equation. The computed, average and local Nusselt numbers are compared with the experimental and LES results reported in the literature. The phase-averaged analysis of the shedding phenomenon is studied to understand the heat transfer phenomenon at different faces of the cylinder and turbulent heat fluxes are also considered to understand the effect of turbulence on convection.
