Study of Numerous Injections into Horizontal Flow Stream at Low Temperature

Abstract

In this paper, the three-dimensional flow and characteristics of numerous injections into horizontal flow stream are examined numerically using CFD with the standard k-? turbulence model following side tee mixing experiments. The model has been validated with experimental results in a side tee mixer in which a side stream mixes with a horizontal stream perpendicularly. A good agreement between simulated and experimental results was obtained. The effects of numerous injections are discussed for this configuration. A reasonable decrease in downward mixing length of horizontal pipe is observed. Other factors such as the tee angle, which enhanced mixing in pipes with side tees, do have a similar impact on mixing in this mutiple tee geometry.
