【摘要】 用盐水示踪、微机采样来研究垂直管道浸取器回弯头内单相流的流动模型。选用扩散模型。将回弯头分解为直管段和回弯两部分。在设备的进口和出口同时检测应答 ,用矩阵法转换成理想脉冲的应答 ,求取回弯的混合扩散参数 ,并作关联。更多还原

【Abstract】 The flow model of single phase flow in the elbow of the vertical tubular leacher was studied by using NaCl solution tracing and microcomputer sampling. The diffusion model was used. The elbow may be resolved into straight section and a bend. The response was detected by sampling from the inlet and outlet of tube section. The impulse response was obtained by matrix method. The mixed diffusion parameter of the return flow point, and their correlation were calculated.更多还原
