| Abstract [eng] |
Heat and mass transfer mathematical model of slipping in humid air droplet was provided, its solution algorithm was discussed and numerical scheme of iterative solution for a droplet transfer parameters calculation was created. Water droplet convective heating cases are defined by initial conditions Tg = 500 K, wg = 10 m/s, p = 0.1 MPa, pv,∞/p = 0.3, T0=278 K and 2R0 = 150∙10-6m, when Reynolds number is 0, 20 and 50. A droplet phase transformation cycle expressed by Fourier time scale was modelled. It was based on, that in unsteady phase transformation mode a heat transfer conditions has essential influence for a droplet thermal and energy states consistent pattern change at phase transformation cycle. |
