Abstract
The pipeline mixing of two fluid streams at an oblique branch was studied to clarify the optimum condition for rapid mixing. The optimum condition as a function of branch angle was experimentally obtained by comparing the varying degrees of a standard deviation of the temperature distribution in the downstream cross-section of the pipe. The condition is discussed on the basis of an empirical trajectory of the deflected jet formed by an injection of secondary flow. The branch-angle dependence of mixing is discussed through comparison of the results at the optimum velocity ratio and through application of one-dimensional analysis of the deflected jet.<BR>As a result, the optimum condition and the jet trajectory were correlated by extending the equations for tee mixing. At the optimum condition for rapid mixing, the jet of the same sign of branch angle shows an almost constant trajectory in its downstream region. The branch-angle dependence of mixing is caused by the jet in the initial stage, and the change in mixing distance from that of optimal tee mixing amounts to the value of the main-pipe diameter. For rapid mixing, a branch angle of about π/4 rad pointed upstream is recommended.
