Experimental investigation of the deposition of liquid droplets on the walls of a vertical cylindrical channel from wall gas-droplet jets
Annotation
The results are given of an experimental investigation of the formation of liquid films from wall gas-droplet jets under quasi-isothermal conditions. The experiments are performed in the initial segment of a round cylindrical tube under conditions of varying cocurrent-flow parameter $m=\rho_s w_s/\rho_0 w_0$ and concentration of liquid droplets. The instantaneous thickness of the liquid film is measured by a capacitive sensor. The distributions of the liquid-film thickness and of the mass rate of particle deposition along the length of the channel are obtained. The pattern of deposition is compared with available data for a stabilized two-phase flow in a tube. Reasons for the difference of the laws of liquid-droplet deposition from wall gas-droplet jets are discussed.
