Abstract

Using supercritical fluid as coolant in a power cycle is generally considered as an advanced solution for energy conversion. When the pressure is above the critical point (P c), thermo-physical properties vary significantly with temperature, which leads to complicated heat transfer phenomena. In the current project, direct numerical simulation (DNS) in a horizontal heated pipe has been developed for supercritical CO2 using the numerical solver based on OpenFOAM. DNS enables us to investigate the detailed turbulence modulation and heat transfer characteristics. The horizontal layout of the pipe leads to a flow stratification, which is not observed in the vertical pipes from the report in the last year. Furthermore, the obtained turbulence data are serving for the development of advanced turbulence models.
