Numerical study on supercritical heat transfer of n-decane during pyrolysis in rectangular tubes

The supercritical heat transfer processes of n-decane during pyrolysis in rectangular tubes having three different equivalent diameters are studied numerically. The effects of mass flow rate (2–5 g/s), heat flux (109–436 kW/m2), and three different channel configurations having the same cross-sectional areas on the supercritical heat transfer characteristics of n-decane during pyrolysis are investigated. The heat transfer mechanisms are analysed...
