...Chao-Kuang Chen; Yue-Tzu Yang; Kuei-Hao Chang In this study, Prandtl’s transposition theorem is used to stretch the ordinary coordinate-system in certain direction. The small wavy surface can be transferred into a calculable plane coordinate-system. The new governing equations of turbulent forced...

...M. M. Molla; L. S. Yao Natural convection of non-Newtonian fluids along a vertical wavy surface with uniform surface temperature has been investigated using a modified power-law viscosity model. An important parameter of the problem is the ratio of the length scale introduced by the power-law...
