Abstract :
Presents experimental and numerical studies of convective heat transfer inside a uterus model simulating the application of a Perfluoro-chemical (PFC) fluid into the endometrium cavity to achieve cryoablation. The numerical prediction is based on a 1-D finite difference method of the bio-heat equation using the Crank Nicolson scheme. The numerical method is first validated by a 1-D physical model by measuring temperature history at several locations within a silicone rubber sheet. The heat flux and heat transfer coefficient of PFC during the process are determined.
