| 摘要: |
| [目的]观测水面油膜粗糙度,以进一步研究水面油膜对后向散射的影响,提高微波监测水面溢油的精度。[方法]采用三维激光扫描仪观测激光垂直扫描油面获得测距数据,多次测量求平均值后再求其均方根误差以实现对油膜粗糙度的观测。[结果]随着含水率的增加,原油张力和粘度逐渐增大,当温度为20~33℃时,其乳化饱和含水率不大于21%,在理想状态下的原油乳化制备过程中,油膜粗糙度与含水率基本呈余弦关系。三维激光扫描仪可在0~6 m/s风速下观测油膜厚度> 0.005 mm的油面粗糙度。[结论]采用三维激光扫描仪观测油膜粗糙度是可行的。 |

| Abstract: |
| [Objective] The roughness of the oil film is observed to further study the influence of the surface oil film on the back scattering and to improve the accuracy of microwave monitoring of oil spill.[Methods] The laser vertical scanning on the surface of oil are observed by 3D laser scanner to obtain the measurement data. The average value of multiple measurements is evaluated and then the root mean square error is obtained to realize the observation of the oil film roughness.[Results] With the increase of moisture content, the tension and viscosity of crude oil gradually increase. When the temperature is 20℃ to 33℃, the saturated moisture content of emulsified oil is not more than 21%. In the ideal state of the crude oil emulsion preparation process, the oil film roughness and moisture content are basically cosine relation. The 3D laser scanner can observe the oil surface roughness > 0.005 mm at 0~6 m/s wind speed.[Conclusion] It is feasible to observe the oil film roughness using 3D laser scanner. |
