Weighted Extended B-Spline Model of Microwave Irradiated Human Eye

Abstract

In this paper, newly developed finite element method with weighted extended b-spline computer modeling have been applied to calculate the corneal surface temperature rise of the human eye during microwave irradiation. The heat conduction model of the microwave-irradiated eye is constructed. The mechanism of heat transfer from the eye and the selection of the thermal parameters of the media of the eye are also discussed. The implementation of these parameters in the weighted extended b-spline solution of the heat conduction is then developed. Furthermore, temperature rises calculations are compared with the studies in the literature examining the distribution of heat in the eye which were exposed to microwaves in different ways.

Mikrodalga Işımalı İnsan Gözünün Ağırlıklı Genişletilmiş B-Spline Eğri Modeli

Abstract

Bu makalede, insan gözünün mikrodalga ışınlaması sırasında kornea yüzeyindeki sıcaklık artışını hesaplamak için yeni geliştirilmiş olan ağırlıklı genişletilmiş b-spline eğrisi sonlu elemanlar yöntemi bilgisayar modellemesi kullanılmıştır. Mikrodalga ışınımlı gözün ısı iletim modeli geliştirilmiştir. Gözden ısı aktarımın mekanizması ve gözün ısıl parametrelerinin seçimi de ayrıca tartışılmıştır. Bu parametrelerin, ısı iletiminin ağırlıklı genişletilmiş b-spline çözümüne gerçekleştirimi oluşturulmuştur. Bunlara ek olarak, sıcaklık artış hesaplamaları, literatürde farklı yöntemlerle mikrodalgaya maruz kalan gözdeki ısı dağılımlarını inceleyen çalışmalarla karşılaştırılmıştır.
