Experimental results on heat transfer characteristics of kerosene at supercritical pressure flowing inside a stainless-steel tube with an internal diameter of 1.70 mm are discussed in this paper. The tests are conducted at pressures of 5
15 MPa
mass velocities of 8500-51000 kg·m -2 ·s -1
and heat fluxes up to 55 MW·m -2 . Enhancement of heat transfer due to pseudo-boiling is found when wall temperature reaches pseudocritical temperature. Deterioration of heat transfer occurs with wall heat flux increasing. The critical heat flux increases when an additive is added into kerosene. At a very high heat flux secondary enhancement of heat transfer occurs
which could limit the deterioration of heat transfer. A turbulent heat transfer correlation for this kind of heat transfer which fits the data well is given.
