Continuum Modeling Perspectives of Non-Fourier Heat Conduction in Biological Systems [PDF]

open access: yesJournal of Non-Equilibrium Thermodynamics, 2021
Abstract The thermal modeling of biological systems is increasingly important in the development of more advanced and more precise techniques such as ultrasound surgery. One of the primary barriers is the complexity of biological materials: the geometrical, structural, and material properties vary in a wide range.
