STUDYING OF INTERRELATIONS OF BLOWING PARAMETERS, OPTIONS OF ELECTRIC INFLUENCE AND NATURE OF LIQUID SPRAYING WITH COLD MODELLING
Abstract
Laboratory researches on studying on physical models of influence of conditions and the modes of a blowing out with the five-nozzle blowing module on the features of liquid spraying are conducted on three zones: near the lance, near the wall and out of model.
The possibility of decrease in level of liquid spraying in the conditions of use of low-voltage electric potential is established, especially at imposition to the lance of positive polarity. It is revealed that start of influence of potential and the maximum value of the useful power allocated in a under the lance zone are defined by a concrete combination of value of pressure before a nozzle and level of lance tip provision.
