Operation of a fluid jet amplifier in the cavitation regime

It is established that a Coanda-effect fluid jet amplifier continues to function in the initial and intermediate stages of cavitation. However, in the separation stage, which extends to the output channels, the effect is disrupted and the amplifier can no longer function normally.Translated from Zhurnal Prikladnoi Mekhaniki i Tekhnicheskoi Fiziki, No. 5, pp. 147–150, September–October, 1970.     

Effect of the Temperature on the Phosphorescence and Absorption Parameters of the Energy Donor in Frozen Paraffin Solutions

The effect of temperature on the luminescence and absorption characteristics of the donor-acceptor benzophenone-naphthalene mixture in a frozen n-octane solution is investigated. The main mechanisms of increase in the phosphorescence intensity of energy donor and acceptor molecules after solution annealing are established.
