摘要
通过粒子成像测速仪对气固两相圆湍射流在相同的Stokes数下、不同颗粒质量浓度比η、不同截面处进行测量,得到了三种不同颗粒质量浓度比η下颗粒的典型图像,以及三种不同颗粒质量浓度比η下颗粒相的轴向速度,径向速度,和湍动能的分布图,并对其进行了分析,得到了气固两相圆湍射流颗粒质量浓度比变化对颗粒相行为影响的一些规律。图5参6。
Typical particle images of gas-solid turbulent cylindrical two phase jet flows were obtained by PIV for 3 different particle mass flow rate ratio η, under same Stokes Number conditions, measured at different cross-sections. Obtained at the same time for three different η values were visual particle images and the particle phases' axial and radial velocity distribution pictures, as well as those of the kinetic turbulence energy, which, through analyzing, revealed some laws that govern the influence of particle mass flow rate ratio η variations on the behavior of the particle phase in gas-solid two phase turbulent cylindrical jet flows.
