Fluids at a supercritical pressure are accompanied by strong variations of thermo-properties, buoyancyinfluences and “abnormal” thermal developments, which have complex and interactive effects on turbulence and heat transfer, making predictions and modelling of such flows a difficult task. In order to isolate effects of variable properties and buoyancy from intricate thermal and flow developments, a vertical channel flow with constant but different wall temperatures is investigated using direct…

The dominant thermal resistance approach for heat transfer to supercritical-pressure fluids

In order to provide improved correlations for cycle analyses of supercritical CO2 power systems, quasi-developed turbulent flow in a duct is simplified to develop semi-analytic treatments of dominant

Direct numerical simulation of turbulent supercritical flows with heat transfer

Turbulent heat transfer to CO2 at supercritical pressure flowing in heated vertical tubes is investigated using direct numerical simulation at the inlet Reynolds number Re0=5400, which is based on

Numerical Analysis of Convective Heat Transfer in Supercritical Water Flow Channels

Abstract In this paper, two-dimensional laminar convective heat transfer of water at a supercritical pressure of 25 MPa in a horizontal rectangular duct has been investigated. The objectives were to
