要約

Modeling of turbulent flow and heat transfer to supercritical pressure fluids in circular tubes is achieved through an integral approach. The model deals with the effects of buoyancy and flow acceleration due to the dramatic property variations in the form of resistance coefficients. A traditional mixing length turbulence model is employed into the numerical scheme. Heat transfer at different flow conditions for both heating and cooling cases is simulated. The numerical model can provide fast predictions for the heat transfer behavior in the turbulent boundary layer of supercritical fluid flows, and the numerical results are compared with the available experimental data for validation.
