  author={Majid Bahrami and M. Michael Yovanovich and J. Richard Culham},
The characteristics of fully-developed, laminar, pressure-driven, incompressible flow in rough circular microchannels are studied. A novel analytical model is developed that predicts the increase in pressure drop due to wall roughness in microtubes. The wall roughness is assumed to posses a Gaussian isotropic distribution. The present model is compared with experimental data, collected by other researchers and good agreement is observed. Nomenclature a = mean radius of rough microtube, m C… CONTINUE READING
