Cryosurgery - temperature distribution problem

March 5, 2007, 05:15

Hi Guys,

Im working on a project that involves Cryosurgery, which is a way to ablate tumors using extreme cold conditions. An iceball is formed within the body and it engolfs the tumor by "killing" its cells. I need to model the temperature distribution within this iceball as a function of time. I want to create a model that will simulate a human tissue (I already have the thermal properties of the tissue) and to define the initial temperature of the tissue to be 37 degrees centigrade. Inside this tissue I want to define a single point that will have a constant temperature (-100 degrees centigrade). The formation of the iceball starts from this point.

I have some problems in defining these initial conditions using the fluent software, and would like to get some advise from U guys.

Cheers, Tal

hai, I am Mtech graduate in Cryogenic Engineering and now I would like to do my Ph.D work in "Heat transfer during Cryosurgery". Can you tell me about your knowledge base and your objective in this area Thanks Rijo

Hai Mr.Tal,
I am also working on cryotherapy in Fluent. I would like to know whether you solve your problem or not? I need a suggestion from you regarding that.
Thankyou.
