And about the former I am rather optimistic."[3]

假设身份没有问题,相关工程专业,私校里Stanford, Caltech, MIT都很出色,公校里
UC Berkeley, UMich, UIUC也还不错。
方向上,可选流体,固体和控制三大方向。流体上大体分计算流体和实验流体两大方向
,可以研究基础的湍流模型,湍流转捩(turbulence transition),engine内部的燃烧
模型,机体或机翼设计,振动模型等等,一般不是机形相关,就是引擎相关的项目。固
体和控制不是内行,印象中固体可以有材料和结构两大块。控制系统和机械,电子和CS
