Abstract

In this paper computational model of the numerical thermal model within the neonatal body cable of controlling the brain cooling process is presented. The main aim of the analysis was to find the proper parameters of the process. The simplified geometric model of newborn's body, consisting of the number of compartments, was built using Design Modeler. The neighbouring compartments exchange heat by conduction through tissues but also interact with each other through flowing blood. To simulate the natural heat transfer processes through the human tissues the Pennes bioheat equation was implemented into Ansys Fluent, using UDF (User Defined Function) capability. Model parameters are determined using inverse thermal analysis.
