ABSTRACT
Now there were different
aspects of heat exchangers of ejectors who could work in broad range of speed
regulation characteristics, and with the different cores and auxiliary substance
flows. For affirming of estimated performances the bench had been project, allowing
to change speed regulation characteristics of a main stream and to regulate
metering characteristics of an auxiliary fluid flow. For affirming of estimated
performances of a heat exchanger of an ejector the imitative bench and with a
view of accident prevention had been project, cooled air and the prepare water actuation
mediums. The bench had been positioned in an insulated cooled room. For
putting off gauging the multifunctional
measuring complex of TESTO 400, was taken the temperature a surrounding medium,
and a water rate does regulate by
us. The high speed photo
cameras were applied to bracing of formation of drips. Strain-gauge balances
apply to determination of mass of water on the shield. The air flow was shape,
and moving in an ejector heat exchanger by means of the axial multiple-speed
fan. The purpose of projection of a heat interchanger of an ejector is maintaining of airspeeds by means of the
ventilator in the mixing chamber 10 to 80 meters per second. The temperature
of given air was a stationary value, equal to -20 °C. Temperature of injection
water was varying from 4 to 20 °C.
