A recent model for condensation in microchannels by the authors has been modified to investigate the effect of channel inclination. Provisional results are obtained for the case studied earlier for horizontal channels i.e. for R134a with saturated vapour at inlet and prescribed uniform wall temperature. Calculations give distributions around the channel perimeter of condensate film thickness and heat flux from which the mean (around the channel perimeter) heat flux and heat-transfer coefficient are found. Results are presented for square channels with side 0.5, 1.0 and 3.0 mm.
