...Zhipeng Duan Slip flow in various noncircular microchannels has been further examined, and a simple model for a normalized Poiseuille number is proposed. As for slip flow, no solutions or graphical and tabulated data exist for most geometries; the developed simple model fills this void and can...

... that q ≈ 0.307 for large tubes and q ≈ 0.5 for microchannels, minichannels, and capillaries. The general characteristics of Eq. 31 are shown in Fig. 4 for a range of values of q . Thus, the extended Turner–Wallis approach is also a one parameter correlating scheme. Awad and Butt...

... and a velocity slip may occur at the duct walls. Noncircular cross sections are common channel shapes that can be produced by microfabrication. The noncircular microchannels have extensive practical applications in MEMS. The paper deals with issues of hydrodynamic flow development. Slip flow in the entrance...

...M. Bahrami; A. Tamayol; P. Taheri In the present study, a compact analytical model is developed to determine the pressure drop of fully-developed, incompressible, and constant properties slip-flow through arbitrary cross section microchannels. An averaged first-order Maxwell slip boundary condition...

...Y. S. Muzychka; J. Edge Non-Newtonian fluid flow in noncircular ducts and microchannels is examined. A simple model is proposed for power law fluids based on the Rabinowitsch–Mooney formulation. By means of a new characteristic length scale, the square root of the cross-sectional area, it is shown...
