“…The fully developed Nusselt numbers for such a rectangular microchannel are obtained and given in Table 1. The results agreed with those of Kuddusi and Çetegen [21], given in Table 2, who studied heat transfer in rectangular microchannels. Note that the results of Kuddusi and Çetegen [21] are for the 3S thermal version that corresponds to the three heated walls in this work.…”

“…Since the developed computer program has the flexibility to simulate the flow in the trapezoidal microchannels with any given apex angle, first, the thermally developing and fully developed Nusselt numbers are calculated for a rectangular microchannel by changing the apex angle from 54.74 • to 90 • . The results agreed with those of Yu and Ameel [20] and Kuddusi and Çetegen [21] who studied heat transfer in rectangular microchannels. This is the first validation of the solution method.…”

“…Axial conduction effects were neglected in all solutions and the simplified energy equation was solved assuming hydrodynamically fully developed velocity profile. Slip-flow heat transfer in rectangular microchannels has been studied by several researches [24][25][26][27][28][29]. Yu and Ameel [24,25] studied laminar slip-flow forced convection under thermally developing flow for constant wall temperature and isoflux boundary conditions.…”

Entropy generation in a rectangular microchannel with fully developed steady gaseous flow at slip flow regime is studied. Two different thermal versions, uniform temperature (H1) and uniform heat flux (H2) on the walls, are considered. Analytically obtained expressions for temperature and velocity fields are used for entropy generation calculations. The effects of rarefaction, geometry, Peclet number Pe and group parameter Br/Ω on entropy generation (irreversibility) and local variation of entropy generation are explored. The main findings are; irreversibility decreases with rarefaction regardless of the thermal versions, irreversibility increases with aspect ratio for H1 thermal version and exhibits very little change with aspect ratio for H2 thermal version. For H1 thermal version the points of maximal entropy generation are at the middle of walls. For H2 thermal version entropy generation is generally high at immediate vicinity of walls and decreases by departing the walls toward the centre of the microchannel.
