Zuhur Alqahtani, Ibrahim A. Abbas, Marin MarinPurpose
The purpose of this study is to analyze the bio-thermal-diffusion interactions in living tissues, using the generalized bio-thermoelasticity with mass diffusion model. The goal is to understand the impact of various factors like blood perfusion rates and thermoelastic models on physical quantities such as temperature, concentration, stress, displacement and chemical potential in biological tissues.
Design/methodology/approach
The study uses the generalized bio-thermoelastic-diffusion equations with two relaxation times, expressed in the Laplace domain. An exponentially decaying pulsed heat flux is applied to the surface and the analytical solution is obtained using eigenvalue techniques. The results are computed numerically and visually represented for various physical quantities, providing insights into the effect of blood perfusion rates and thermoelastic models.
Findings
The numerical results demonstrate the influence of blood perfusion rates and different thermoelastic models on the temperature, concentration, stress, displacement and chemical potential in biological tissues. The impact of bio-thermal-diffusion interactions on wave propagation in tissues is clearly illustrated through graphical representations.
Originality/value
This study provides valuable insights into the biomedical responses related to bio-thermal-diffusion interactions in biological tissues. It contributes to the understanding of how heat flux, diffusion and blood perfusion influence the physical properties of tissues, which is essential for improving biomedical treatments and therapies. The use of graphical representations helps in visualizing the effects of various models and conditions.
