The characteristics of flow and heat transfer of shell-and-tube heat exchangers with overlapped helical baffles (STHXsHB) were illustrated through a theoretical analysis and numerical simulation. The ideal helical flow model was constructed to demonstrate parts of the flow characteristics of the STHXsHB, providing theoretical evidence of short-circuit and back flows in a triangular zone. The numerical simulation was adopted to describe the characteristics of helical, leakage, and bypass streams. In a fully developed section, the distribution of velocity and wall heat transfer coefficient has a similar trend, which presents the effect of leakage and bypass streams. The short-circuit flow accelerates the axial velocity of the flow through the triangular zone. Moreover, the back flow enhances the local heat transfer and causes the ascent of flow resistance. This study shows the detailed features of helical flow in STHXsHB, which can inspire a reasonable optimization on the shell-side structure.

磁控螺旋形微纳米机器人可在低强度旋转磁场(<10 mT)的驱动下,实现亚微米精度的三维(3D)游动。由于低强度磁场对细胞和组织无害,磁控螺旋形微纳米机器人在生物医学方面有很大的应用前景,如微创手术、细胞操作和分析以及靶向治疗。本文系统介绍了磁控螺旋形微纳米机器人的制造方法、运动控制和生物医学应用。

流动,是物质(如铜、铝等)流动和流体流动二者所具有的基本特征,基于这个论点,简要地回顾了流体力学中研究流体流动的两种方法,即拉格朗日法和欧拉法;相应地提出了物质流分析的两种方法,即跟踪观察法和定点观察法。由于前者在文献中未见报道,因此对它进行了重点说明。强调了物质流的跟踪观察法既适用于稳态物质流(产品产量不变),也适用于非稳态物质流(产品产量增长或下降)。以钢铁产品生命周期的铁流图为例,说明了物质流的跟踪模型。在引入了物质流的非稳度后,提出了物质流各项指标的计算式,以及它们之间的相互关系。以瑞典铅酸电池系统为对象,计算了其中铅流的各项指标,并进行了必要的分析。
