Research progress of flow field characteristics in impinging stream reactor
摘要
Abstract
The features of velocity field and pressure fluctuation in impinging stream reactor were summarized in the paper.The radial velocity,axial velocity and oscillation behavior in the unconfined impinging stream reactor were studied systematically.The oscillatory modes of the stagnation points were divided.And a large number of velocity correlation formulas suitable for different nozzle distance were obtained,but the mechanism of oscillation was not clearly explained.With the increase of the Reynolds number in the laminar flow state,many scholars had divided the flow type in the confined impinging stream reactor,and proposed the critical parameter correlation of engulfment flow.Due to the change of the structure parameters,there was no universally applicable correlation.The impinging zone and the flow field pattern were determined by non-linear analysis in the submerged impinging stream reactor.However,the mechanism of energy distribution and velocity signal in the turbulent flow field cannot be revealed.The trends of research on flow field in impinging stream reactor were also pointed out.关键词
