چکیده
In this paper the finite element method is used for the numerical simulation of two dimensional transient bioheat transfer process in the human eye. The human eye is modelling as a composition of several homogeneous regions. On the outer surface the heat radiation is assumed, on the inner surface the Robin condition is accepted. In the final part of the paper the results of computations are shown. 1. Theoretical model of human eye In Figure 1 can be seen that the eye is approximately a spherical organ. The back surface is covered with a thin membrane (retina), that is permeated with blood vessels and is connected with the brain by the optic nerve. Under the retina is a layer called the choroid which serves to nourish it. The anterior transparent surface of the eye is a cornea. The lens lies between the aqueous humour and vitreous humour. The aqueous and vitreous humours are transparent liquids with different concentrations of NaCl [1, 6, 7]. Fig. 1. Model of a human eye

Effect of Pullback Speed and the Distance between the Skin and Vein on the Performance of Endovenous Laser Treatment by Numerical Simulation
Introduction: Endovenous laser treatment (ELT) is a new treatment method for the reflux of the great saphenous vein. A successful ELT is dependent on the selection of optimum parameters required to achieve optimal vein damage while avoiding side effects including skin burns. The mathematical modeling of ELT can be used to understand the process of ELT. This study was conducted to examine the ef...
متن کاملTransient bioheat simulation of the laser-tissue interaction in human skin using hybrid finite element formulation.
This paper presents a hybrid finite element model for describing quantitatively the thermal responses of skin tissue under laser irradiation. The model is based on the boundary integral-based finite element method and the Pennes bioheat transfer equation. In this study, temporal discretization of the bioheat system is first performed and leads to the well-known modified Helmholtz equation. A ra...
متن کاملBioheat transfer in the human eye: a boundary element approach
A boundary element method is applied for the numerical solution of a boundary value problem for a two-dimensional steady-state bioheat transfer model of the human eye. The human eye is modeled as comprising four distinct homogeneous regions. The boundary condition on the outer surface of the cornea is non-linear due to heat radiation. An iterative approach is used to treat the non-linear heat r...

In the present work, the solidification process was simulated in both macroscopic and microscopic scales. Two-dimensional heat transfer equation for conduction was applied for macroscopic modeling using enthalpy formulation and finite element method.

In the present work, a meshless method called Finite Point Method (FPM) is developed to simulate the solidification process of a continuously cast steel bloom in both primary and secondary cooling regions. The method is based on the use of a weighted least-square interpolation procedure. A transverse slice of the bloom moving at casting speed is considered as the computational domain and two di...
