摘要
研究不可压缩粘性流体,在双曲拉伸面上的边界层流动及其热传导.分别使用级数展开法和局部非相似(LNS)法,得到解析结果和数值结果,给出了表面摩擦和Nusselt数的解析结果和数值结果,并进行了互相比较.同时发现动量和热边界层厚度,随着离前缘距离的增加而减小.众所周知,线性拉伸项方程的解,可以作为双曲拉伸首次项方程的解.
The boundary layer flow and heat transfer analysis of an incompressible viscous fluid for a hyperbolically stretching sheet was presented. The analytical and numerical results were obtained using series expansion method and local non-similarity （LNS） methods respectively. Analytical and numerical results for skin friction and Nusselt number were calculated and compared with each other. The significant observation was that the momentum and thermal boundary layer thicknesses decrease as the distance from the leading edge increases. The well known solution of linear stretching was found as the leading order solution for the hyperbolic stretching.
