Computational investigation on turbulent heat transfer of supercritical CO2 in the half-roughen horizontal pipe

To address the heat transfer degradation that occurs in the top section of horizontal pipes when sCO2 fluid flows are heated, the upper half wall with higher temperatures is particularly roughened using uniform sand-grain roughness. The SST k−ω model is validated and used to simulate the horizontal...
