Keywords:

heat- and mass-transfer; evaporation of binary composition drops


Abstracts:

Distribution of temperature and gas concentration on axes and channel wall are considered under the influence are only coefficient as flow regime, density ratio of both streams, swirl degree of peripheral jet. Experiments were conducted in the cylindrical channel 46 mm diameters and 1.2 m length with annular slot 2 mm height at the entrance. The peripheral stream was swirled by spiral fin relative to axial direction at the angle of 00, 580, 740 и 860. The Reynolds number range based on the main stream was (0.15 ÷ 27)·104. Coaxial jet temperatures were different in the thermal test nearly 600. The wall jet of argon or helium was input for measuring foreign gas concentration on pipe wall, helium was used as main stream.
