Temperature Dependence of Physical Properties for Thermal Fluid Analysis of PCB Hydrothermal Oxidation Decomposition Reactor

Abstract

To elucidate the corrosion mechanism on the inner wall of the bottom of a hydrothermal oxidation decomposition reactor that decomposes hazardous polychlorinated biphenyls (PCB) at high temperatures and pressures. The finite volume analysis using OpenFOAM has been used to analyze the coupled thermal flow of a mixture of PCB and water, and the heat transfer between internal fluids and the reactor vessel. In this paper, we discuss the effect of the temperature dependence of physical properties such as density and viscosity of PCB and water.
