摘要
本文提出了一种数值求解人体生物热方程时边界条件的处理方法,该方法以生物传热学理论为基础,通过引入“当量皮肤温度”T_(tb),对皮肤层内的生物热方程作了适当修改,并且推导出了采用交替变换方向法(Alternating direction implicit method)求解人体温度场时,边界节点的离散方程。
A treatment method of the boundary condition of the human body bio-heat equation is presented,based on bioheat transfer and a lot of medical investigations.An equivalent skin temperatare,Ttb,is introduced into the bio-heat equation for improving calculation of blood convection heat transfer in the skin layer.ADI Method(Alternating Direction Implicit) is used to obtain the numerical solution of the human body bio-heat equation.Authors derive discrization equation for the boundary nodes.
