| Abstract | Fluid velocities in a continuous-flow, cylindrical, supercritical-water reactor are examined and mathematically modeled using a simplified Navier-Stokes equation. Within the system, a large number of moles of small gaseous species are generated from large molecules of JP-8 jet fuel, causing the fluid to accelerate through the length of the reactor. This net increase in moles leads to a nonconstant fluid density and is modeled using the Peng-Robinson equation of state. Several assumptions are made to make this system readily solvable. The simulation results show that the density change and net generation of moles lead to significant increases in the fluid velocities as the products move down the reactor. Typical reactant feed rates of JP-8 jet fuel (0.5 gmin(-1) and 1.0 gmin(-1)) are modeled based upon previous experimental data performed in a tubular reactor with a length of 75.6 cm and an inner diameter of 2.54 cm. |
