Experimental study of heat transfer and wall shear stress in an upward bubbly flow in an inclined flat channel is presented. The measurements were performed in the range of superficial liquid velocities 0.3÷1.1 m/s and different values of volumetric gas flow rate ratio. Measurements of hydrodynamic structure were carried out by electrochemical method using a miniature sensors of friction. The values of average friction and heat transfer coefficient at different orientations of the channel were determined. It is shown that there is a significant dependence of friction and heat transfer on the channel inclination angle in the gas-liquid flow. Keywords:
