Abstract Deeply analysis and prediction of turbulent convection heat transfer of supercritical pressure fluid in one-side non-uniform heating vertical tube plays a major role in system design and security. The Over-prediction of convection heat transfer of supercritical pressure fluid in vertical tube is attributed, at least partly, to the invalid of turbulent model on simulating the buoyancy effect. The present paper adopt an improved turbulent model, which is validated suitable to three dimensional model, to simulate flow and heat transfer of supercritical pressure water in vertical non-uniform heating tube. Heat transfer deterioration phenomenon occurs in non-uniform… More >
