A fractal analysis of laminar flow resistance in roughened microchannels

The fractal geometry theory and method are used to simulate the rough surface topography. The pressure gradients, friction factors and Poiseuille numbers for laminar flow through microchannels with roughened surfaces are derived. The proposed fractal models for the relative increases of the pressure...
