Experimental and simulation study of atomization concentration of corrosion inhibitor in a gas pipe

The aim of present study is to investigate the atomization distribution of corrosion inhibitor in the gas pipe via experiments and numerical simulations. The apparatus was set up to study the atomization parameters and concentration. A discrete phase model was applied to study the droplets distribution. The results reveal that the droplets size and atomized angle are closely related to the injection pressure. A higher pressure can contribute a greater atomization field. With the effect of gas flow, the inhibitor droplets would disperse in the pipe and adhere to the inner wall. But the top of pipe is easily absent from the inhibitor film. A modified Longwell diffusion model is developed with the consideration of gravity settling and relaxation theory, with an average experimental deviation of 12.86% or less.
