Left image shows cut-away of CFD multiphysics transient analysis of saturated wick heated with metallic coil.
Coil is activated by applied voltage modulated with proprietary algorithm.
Airflow and resulting air temperatures are also calculated based on simulated user-applied vacuum.
Above image shows single frame of IR thermographic movie taken from upstream side of wick and coil of vaping device during a puff sequence.
Left image shows IR thermography measured peak wick and coil temperatures during a multi-puff sequence, demonstrating effective TCR-based temperature control.
