简介:熔化力量输出不仅与参予反应的燃料粒子数字密度而且到熔化反应率系数成正比(或反应),它依赖于反应物速度分发功能。他们通常被假定是有为热核聚变情形的一样的温度的双Maxwellian分发功能。不管多么高驱动中立横梁注射和少数离子种类ICRF血浆加热,或多拧的血浆横梁迎头向前的碰撞,在收敛,区域在未来被要求并且调查大规模熔化反应堆,当时,源于电离或费用交换的注射精力充沛的快离子尾巴的部分将足够大,他们对non-Maxwellian分发功能的贡献不是可以忽略的,因此评估fu的系数或计算到熔化反应在如此的情况,横梁目标,和横梁横梁反应改进中,效果贡献应该起很重要的作用。在这份报纸,为不同横梁和目标联合情形计算熔化反应率系数的几个有用公式详细被导出。

简介:随煤气的汽轮机的入口温度的增加,由使用常规方法的好处是可能的接近他们的限制。因此,学习为超过这些当前的限制使方法凉下来的新奇电影是必要的。基于热转移改进的理论,由使溪流凉下来与化学反应使方法凉下来的一部电影被建议。以便测试建议方法的可行性,数字模拟被进行了。有30度洞的经典的扁平的板结构被用于模拟。在现在的学习,在与使有效性凉下来的电影上的化学反应的关系的参数的效果例如化学的热水池,卷变化,和反应率,数字地被调查。冷却的常规电影也为比较被计算。电影冷却有效性由于化学反应显然被改进的结果表演,和反应热和冷却的反应率流在电影有效性上有重要效果。然而,卷变化的效果能被忽略。
