Slug Flow-Heat Transfer in Parallel Plate Microchannel Including Slip Effects and Axial Conduction

In this paper the forced convection with slug flow model in parallel plate microchannel is studied. In the slug flow model, it is assumed that the velocity of the fluid is uniform across any cross-section perpendicular to the axis of the microchannel. The microscale analysis is taking into account by including the jump temperature at the surface. The axial conduction within the fluid is included but the viscous dissipation is neglected. The energy equation is solved by finite integral transform technique. The isoflux and isothermal boundary conditions were applied. The local and fully developed Nusselt numbers have been obtained in terms of the Knudsen number and Peclet number.
