Abstract: | Intensities of heat and mass transfer for continuous and pulse spray in interaction with the vertical surface of a heat exchanger
differ considerably from one another when the time-averaged spraying rate 1–6] is kept constant. This difference is determined
by characteristic properties of gas-drop flows of continuous and pulse sprays and their interaction with the heat-exchanging
surface. Results of experimental studies of basic hydrodynamic parameters of pulse drop flow are presented: velocity and drop
size dispersions, spectral characteristics of the kinetic energy of the spray at various distances from the source, and influence
of the gas concurrent flow on these parameters. A difference in the heat transfer is shown upon variation of the pulse drop
flow parameters from the heat transfer at the stationary supply of spray. |
