Abstract

In this paper we present a numerical three dimensional (3D) simulation of transient heat transfer process in the human eye. A finite element method is applied to obtain the solution of a boundary value problem for a 3D transient heat transfer model in the human eye. The human eye is modeled as a composition of several homogeneous regions. The Ritz method in the finite element method is used for solving heat differential equation. Applying the boundary conditions, the heat radiation condition and the Robin condition on the cornea surface of the eye and on the outer part of sclera are used, respectively. Simulation results of two and three dimensional models are compared.
