简介：在laminar的非线性的传送对流的效果三维的Oldroyd-B液体流动被探讨。热转移现象被考虑非线性的热放射和热产生/吸收探索。边界层假设被考虑管理流动分析的数学模型。一些合适的类似变量被介绍把部分微分方程转变成平常的微分系统。有射击方法的Runge-Kutta-Fehlberg第四顺序、第五顺序的技术被用来获得无尺寸的速度和温度的答案。液体速度和温度上的各种各样的物理参数的效果被阴谋并且检验。比较与准确并且homotopy不安答案被做为粘滞液体大小写，和一根优秀火柴被注意。墙的数字价值砍在墙的压力和热转移率被公布并且调查。在德卜拉数字的价值的改进在液体速度上显示出反向的行为。当非线性的传送对流参数增加时，结果证明温度和热边界层被减少。Nusselt数字的价值比处于线性放射状况的那些处于非线性的放射状况是更高的。

简介：有高顺序的边界条件为秒顺序产生的液体结构相互作用的域里的问题的一个大类部分微分方程。各种各样的方法正在被使用处理与Laplaces方程联系的这些种混合边界值问题(或Helmholtz方程)在通过固体或液体宣传的波浪的学习产生。在波浪结构相互作用的广泛地使用的方法之一是多极扩大方法。这扩大包含一个常规波浪，波浪来源，波浪偶极子和常规没有波浪的部分的一般联合。没有波浪的部分能进一步以作为没有波浪的潜力被称为的没有波浪的多极被扩展。这些是Laplaces方程或二维的Helmholz方程的单个答案。这些没有波浪的潜力和多极的建设为象二维的非倾斜、倾斜的波浪那样的很多种状况以一种系统的方式这里被介绍，在有有部分衍生物被考虑的更高的顺序的免费表面状况的二层的液体的三个维的波浪。特别地，这些被获得面对作为一个薄有弹性的盘子建模的一个冰封面在免费表面并且也表面紧张的存在的效果考虑。另外为限制大小写，多极和没有波浪的潜在的功能走向单个层多极和没有波浪的潜力，这能被显示出。
