The aim of this study is to understand the thermal behaviour at the inlet of a hydrothermal oxidation reactor. This reactor was designed to eliminate charged waste water and operating in turbulent flow to limit corrosion at the injection points. Three numerical modelling were carried out to simulate the thermal behaviour of the reactor. The first program simulates the reactor operating in turbulent flow...
