将守恒型单调迎风格式(MUSCL)和双曲正切界面捕捉(THINC)算法组合到一起进行数值重构,并通过重构建立新的算子。重构的算子主要作用是尽可能降低网格的边界差商。在MUSCL和THINC算法下,网格左右边界处的状态可以导出一个优化算法的差商判定机制。再按照这一边界差商优化值最小(BVD)的原则,对MUSCL和THINC进行二选一。在BVD重构算子的作用下,数值断面变得平滑,并且有效地限制振荡。BVD重构算子的计算性能将通过一维和二维数值算例来进行检验。

随着世界经济的全球化发展,海运运输成为一种经济实用的运输方式。海运运输的发展离不开各种各样的船舶。船舶在水中行驶时,由于海水是黏性液体,因此会受到阻碍作用,故而会产生船舶阻力。为了提高船舶在海水中行驶的速度,同时降低燃油消耗,因此需要对船舶阻力进行计算。船舶的种类不同,其型线就不同。型线不同自然导致其与水的接触面积不同。因此,针对不同船型的种类,其船舶阻力的计算方法也是不同的。预测船舶阻力的计算方法可以按照船体类型划分为不同的计算类型,分别有适用于滑行艇阻力预测的算法、适用于排水型船舶阻力预测的算法、适用于游艇阻力预测的算法以及细长体理论。探讨结果说明,不同算法和理论适用于不同的船体类型,也有其特定的适用范围。

针对中药滴丸的生产过程,提出一种基于机器视觉的生产控制系统,并通过模糊控制算法实现中药滴丸的控制。其中,以中药银杏叶滴丸为对象,首先通过机器视觉系统采集中药滴丸图像,通过轮廓提取、液滴图像特征参数计算等,实现滴丸大小均匀的控制;利用模糊控制算法对液滴周期时间进行控制,并通过控制温度及液滴图像特征参数来间接控制丸重。实验结果得到,当液滴周期设定值为2秒时,控制作用使得液滴周期时间第2次进入稳定范围±5%后在稳定范围内保持了长达70分钟,可以表明,本研究的机器视觉控制方案能有效控制液滴周期时间,且通过液滴周期时间的调节,实现滴丸的标准化生产,达到控制目的。
