| 摘 要： | 以流体力学基本理论为基础,对深水网箱的水动力阻力进行估算。用理想化的模型代替复杂多变的模型,把网箱所受阻力分为直杆、圆环、网衣3个部分,忽略其余部分的阻力。通过数学拟合得出简化的公式,误差被控制在允许的范围内。运用所得公式,按步骤对一网箱实例进行理论估算。比较模型试验与理论计算值,理论值一般比模型试验所得的网箱水阻力小10%左右。网箱各尺寸参数影响网箱的水动力特性。

| Abstract: | The hydrodynamic resistance theoretical calculation of the submersible cage based on the basic theory of fluid mechanics.Using an idealized model to replace the complex and ever-changing model,the resistance of the cage suffered is divided into three parts: spar,round rim,and the fishing net,ignoring the rest resistance caused by other parts.Gain a simplified formula through mathematical fitting tools and keep the error in allowed limits.Estimate an example of cage step by step making use of the formula.Compared the theoretical calculation with the model test,the hydrodynamic resistance of theoretical value is sometimes lower than the model test 10%.The parameters of cage size have an effect on the hydrodynamic characteristics. |
