摘要
应用特解边界元法对非稳态的三维Pennes方程求解 ,将解分为一满足泊松方程的通解与一特解之和 ,通解按照边界元法求解 ,特解用分离变量法给出 ,与位置有关的部分采用截断多项式 .逐时间段计算边界元的温度及热流值 ,然后计算域内点的值 .并将该方法用于热疗温度场的数值实例计算 .
Particular solution BEM is used to solve three-dimensional Pennes equation.The solution is devided into the common solution of Poisson equation and the particular solution.The common solution is solved by BEM while the particular solution is given by the method of separation of variables.Temperature and heatflux are computed piecewisely in each time step and then the value on the nods in the field is computed.Numerical simulation of cancer hypothermia is given based on this method.
