Corina Fetecau, C. Fetecau, A. Mahmood, E. Axinte

摘要:

建立了由恒定加速板引起的Oldrophil-B流体运动所对应的耗散、壁面剪应力功率和边界层厚度的精确和近似表达式。作为一般结果的极限情况,得到了Maxwell流体、牛顿流体和二阶流体作相同运动时的类似表达式。四种模型的特点是强调通过渐近近似。

英文摘要:

Exact and approximate expressions are established for dissipation, the power of the shear stress at the wall and the boundary layer thickness corresponding to the motion of an Oldroyd-B fluid induced by a constantly accelerating plate. The similar expressions for Maxwell, Newtonian and second grade fluids, performing the same motion, are obtained as limiting cases of our general results. The specific features of the four models are emphasized by means of the asymptotic approximations.
