 Full text | Abstract: This paper presents the theoretical basis for the determination of the eld of velocity of the free air stream owing out of a cylindrical and two-gap skewed jet. Based on this, calculation of the air velocity distribution in the stream’s axis was carried-out. Good agreement was achieved be- tween the values of theoretical and experimental results obtained. The theoretical dependences were adapted to the jets applied in textile technologies. A formula is given for the calculation of the velocity distribution of air owing out from the two-gap skewed jet applied in the melt-blown method. The correctness of the formula given is certified by the results computed as well as by those of the measurements. |
