The results of experimental investigations of pressure gradient in a two-phase adiabatic flow in tubular minichannels are presented. The air-water mixture was used as a working fluid. Eight stainless steel tubular minichannels with internal diameters d[w] = 1.05 - 2.30 mm and section length 300 mm were used. The investigations were conducted in the following parameter range: mass flow rate of water 0.65 - 59 kg/h, mass flow rate of air 0.011 - 0.72 kg/h, mass fraction of air in the two-phase mixture x = 0.0003 - 0.22, and total mass flux (w[rho]) = 139 - 8582 kg/(m[^2] s). It was found, on the basis of the experimental investigations, that commonly used methods of evaluation of pressure drop in a two-phase flow provided poor results. It is therefore necessary to make some modifications to suit the description of two-phase flow in minichannels.
