In this pyrolysis machine, heat transfer follows a complex pattern through a multi-chambered heat exchanger design. The CFD visualization shows high-temperature flow entering and exiting the main reaction chamber, with internal baffles creating turbulent flow patterns to maximize thermal contact.
The inlet graph reveals rapid temperature stabilization, reaching normalized value 1.0 within 150 seconds, while axial velocity (Uz) initially spikes before declining to zero. This suggests complete energy transfer from initial momentum to thermal energy within the system.
Comparing with the outlet graph , we observe the temperature profile exhibits an interesting oscillatory behavior. Temperature peaks around 100 seconds, then drops to approximately 0.55 before gradually increasing to stabilize around 0.72 of the inlet temperature. This indicates significant heat extraction or utilization within the process.
Flow redistribution is evident across the system. While axial velocity (Uz) diminishes at the inlet, it maintains a stable value of 0.88 at the outlet. Meanwhile, lateral velocities (Ux, Uy) establish equilibrium at approximately 0.38 and 0.08 respectively, confirming the complex three-dimensional flow patterns through the chambers.
The temperature visualization confirms effective heat transfer, with coolest regions (blue) in the central processing chamber and hottest regions (red) at the inlet/outlet pipes. This temperature gradient powers the pyrolysis reaction while maintaining controlled conditions within the reaction zone.
