| 摘要: |
| 采用盐水示踪、微机采样来研究垂直管道浸取器直管内单相流的流动模型。选用扩散模型,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,用非线性最小二乘法回归,求出直管的混合扩散系数,并作关联。 |

| Abstract: |
| The flow model of single phase flow in the straight tube of the vertical tubular leacher was studied by using NaCl solution tracing and microcomputer sampling.The diffusion model was used.The response was sampled from the inlet and outlet of tube section.The impulse response was derived with matrix method,the mixed diffusion cofficient of straight tube was evaluated with least squares in the time domain,and corrlation was conducted too. |
| Key words: vertical tubular leacher single phase flow flow model mixed diffiusion coefficient |
