Aquatic suction feeding in vertebrates involves extremely unsteady flow, externally as well as internally of the expanding mouth cavity. Consequently, studying the hydrodynamics involved in this process is a challenging research area, where experimental studies and mathematical models gradually aid our understanding of how suction feeding works mechanically. Especially for flow patterns inside the mouth cavity, our current knowledge is almost entirely based on modelling studies. In the present paper, we critically discuss some of the assumptions and limitations of previous analytical models of suction feeding using computational fluid dynamics.
脊椎动物的水生吸食式进食涉及极其不稳定的流动,包括扩张口腔外部和内部的流动。因此,研究这一过程中涉及的流体动力学是一个具有挑战性的研究领域,在这个领域中,实验研究和数学模型逐渐帮助我们理解吸食式进食的机械原理。特别是对于口腔内部的流动模式,我们目前的知识几乎完全基于建模研究。在本文中,我们使用计算流体动力学批判性地讨论了先前吸食式进食分析模型的一些假设和局限性。
