Numerical Modelling of Hyperthermia and Hypothermia Processes

Abstract

In the paper the results of different numerical solutions of bioheat transfer problems are presented. The base of numerical algorithms constitute the models containing the bioheat transfer equation (or equations) and the adequate geometrical, physical, boundary and initial conditions. In the first part of the paper the solutions concerning the transient temperature field in the biological tissue subjected to the strong external heat sources (freezing, burns) are presented. Next, the examples of sensitivity analysis application in the range of bioheat transfer are discussed. In the final part of the paper the inverse problems are formulated and the example concerning the identification of thermal parameters is shown.

Allogeneic vs. Autologous Skin Grafts in the Therapy of Patients with Burn Injuries: A Restrospective, Open-label Clinical Study with Pair Matching

“…The depth of burn injury is one of the factors determining both the mortality and the manner of treatment [16][17][18]. The procedure of early resection of necrotic tissue combined with autologous or allogeneic skin graft improved the survival outcomes of the patients [19,20].…”

1D generalized dual-phase lag equation. Sensitivity analysis with respect to the porosity

“…[1][2][3][4][5][6][7][8]. One of them is the dual-phase lag equation [9][10][11] in which two time parameters τ q and τ T appear.…”

Sensitivity of transient temperature field in domain of forearm insulated by protective clothing with respect to perturbations of external boundary heat flux

“…The transient temperature field in tissue subdomains is determined by a Fourier-type equation called the Pennes equation [1][2][3][4][5]. This equation contains two additional components (the source functions) connected with the blood perfusion and metabolism.…”
