Numerical Method and Analysis of Computational Fluid Mechanics for Photoelectric Semiconducting Detector
【摘要】 对三维光导型半导体探测器瞬态问题的计算流体力学数值模拟,提出了一类修正迎风分数步差分格式.应用变分形式、能量方法、归纳法假定、微分方程的先验估计理论和技巧,得到最佳阶误差估计.该文数值方法已成功地应用到光导型半导体探测器瞬态问题的数值模拟中.
【Abstract】 For computational fluid mechanics simulations of a three-dimensional photoelectric semiconducting detector,a modified upwind finite difference fractional step scheme was proposed.The optimal error estimated by using techniques including calculus of variations,energy method,induction hypothesis,and a prior estimates were obtained.The proposed scheme has been applied to simulate the photoelectric semiconducting detector.
