飞机播撒催化剂扩散问题的数值解法

NUMERICAL SOLUTION TO THE DIFFUSIVE PROBLEM OF THE CATALYTIC AGENT RELEASED BY THE AIRPLANE

摘要: 本文利用有限差分法对飞机播撒催化剂的扩散问题进行了求解.在题解中考虑了催化剂质点的下落速度随高度的变化,并将该法与解析解法计算的结果进行了对比分析,找出了它们之间的异同.

Abstract: By using the finite-difference method,a solution is obtained in this paper to the diffusion problem of the catalytic agent released by the airplane.The changes of falling speed of the catalytic agent with altitude are taken into full consideration,and their variations in change are found.The results of this method are compared with those of the analytic solution.
