Abstract

This paper systematically investigated the bionic fractal baffle micromixers based on Murray's Law. It focused on the influence of Murray's Law fractal parameters on the mixing performance of bionic fractal baffle micromixers. We varied Murray's Law fractal parameters such as Murray's Law fractal order, distribution position of fractal baffles, Murray's Law initial length, and the number of fractal baffles. The results indicated that increasing the fractal order, adopting an interleaved arrangement structure, increasing the initial length, and employing a larger number of fractal baffles can significantly improve the mixing performance, with mixing efficiency reaching 98.92% at = 100. Furthermore, the reason for the significant enhancement of mixing performance lies in the influence of Murray's Law fractal parameters on the number and area of vortices. This study establishes a theoretical foundation for understanding the interaction between fractal parameters and mixing performance in bionic fractal baffle micromixers based on Murray's Law.

基于默里定律的仿生分形挡板微搅拌器搅拌性能透视图

本文系统研究了基于默里定律的仿生分形挡板微搅拌器。重点研究了默里定律分形参数对仿生分形障板微搅拌器搅拌性能的影响。我们改变了默里定律分形参数，如默里定律分形阶数、分形障板分布位置、默里定律初始长度和分形障板数量。结果表明，增加分形阶数、采用交错排列结构、增加初始长度和采用更多的分形障板可以显著改善混合性能，在 = 100 时混合效率达到 98.92%。此外，混合性能显著提高的原因还在于默里定律分形参数对涡流数量和面积的影响。这项研究为理解基于墨累定律的仿生分形挡板微搅拌器中分形参数与搅拌性能之间的相互作用奠定了理论基础。

期刊介绍： International Communications in Heat and Mass Transfer serves as a world forum for the rapid dissemination of new ideas, new measurement techniques, preliminary findings of ongoing investigations, discussions, and criticisms in the field of heat and mass transfer. Two types of manuscript will be considered for publication: communications (short reports of new work or discussions of work which has already been published) and summaries (abstracts of reports, theses or manuscripts which are too long for publication in full). Together with its companion publication, International Journal of Heat and Mass Transfer, with which it shares the same Board of Editors, this journal is read by research workers and engineers throughout the world.
