氦屏蔽效应的计算机模拟

摘要

The analyses of kinematic process of the "helium blanketingeffect (HBE)" were performed. With the simulation of the kinematic process the authors got a better understanding of the mechanism of HBE: HBE is a diffusion limited mass transfer process, the existence of line limitation is the main factor leading to the appearance of HBE. The "bulk flow"(BF) model proposed by Ortman could predicate the blanketing pressure, however, It did not describe the kinematic process of Hydrogen absorption.%通过计算机模拟，对氦屏蔽效应(HBE)进行了运动学过程的分析。HBE过程是分子扩散迁移限制的过程，而管道限制的存在是HBE能够显现的装置因素；该模型能够很好地解释实验结果。Ortman的“整体流”模型只能在宏观上预测屏蔽压强，而不能对吸氢的运动学过程进行描述。
