Three-Phase-Lag Bio-Heat Transfer Model of Cardiac Ablation

Significant research efforts have been devoted in the past decades to accurately modelling complex heat transfer phenomena within biological tissues. These modeling and analysis assisted a better understanding of intricacies associated factors that affect treatment outcomes hyperthermic therapeutic procedures. In this contribution, we report three-dimensional non-Fourier bio-heat model cardiac ablation accounts for three-phase-lags (TPL) propagation, viz., lags due flux, temperature gradient, thermal displacement gradient. Finite element-based COMSOL Multiphysics software has utilized predict distributions volumes. A comparative conducted variation considering different models. The effect variations magnitude phase systematically investigated. fidelity integrity developed evaluated by comparing results with analytical recent studies available literature. This study demonstrates importance tissue predicting more characteristics important efficient application therapies.
