Abstract
The understanding of body temperature distribution and the comprehension of the effect of therapeutic heat treatment on the body temperature behavior represent major advancements in healthcare. However, obtaining experimental data on the topic has been proven difficult because it is an invasive procedure, restricted to only a few points in the living human body. These setbacks are overcome using numerical simulation, which is seeing increasing applications in healthcare. This study aimed to obtain a 3D geometric model of the human knee joint and the temperature profile on this model in neutral thermal conditions and steady state based on the bioheat equation published by Penne. The geometric model was built based on cross sectional photos from a human body obtained from the Visible Human Project dataset and developed in a Computer Aided Design. A Computational Fluid Dynamics analysis was performed based on the finite volume method. Each tissue presented in the model was characterized by its thermodynamic and physical properties such as: heat conductivity, specific heat and density. The numerical results determined in simulations were within the expected range of temperature for the human knee and similar to the results reported in the literature for similar conditions to those that were used in this study.
