Physical Model Used to Visualize Heat Generation and Heat Transfer Inside the Human Body

Abstract

The paper is concerned with a model of the human body which is made from high molecular gel containing a nonionic surface active agent. The physical model is used to visualize thermal phenomena related to heat generation or heat transfer in the human body. The model shows good transparency below the specific temperature called the "clouding point". However, if temperature is increased as a result of absorbing energy, the region of elevated temperature becomes white and opaque due to segregation of the nonionic surface active agent. In this paper, a method used to develop the model that has the desired physical properties such as the clouding point, electric and thermal conductivity, viscoelasticity and other characteristics, is presented. The high molecular gel model should be useful for visualizing thermal phenomena in the human body.
