This comparative review highlights the relationships between the disciplines of bloodstain pattern analysis (BPA) in forensics and that of fluid dynamics (FD) in the physical sciences. In both the BPA and FD communities, scientists study the motion and phase change of a liquid in contact with air, or with other liquids or solids. Five aspects of BPA related to FD are discussed: the physical forces driving the motion of blood as a fluid; the generation of the drops; their flight in the air; their impact on solid or liquid surfaces; and the production of stains. For each of these topics, the relevant literature from the BPA community and from the FD community is reviewed. Comments are provided on opportunities for joint BPA and FD research, and on the development of novel FD-based tools and methods for BPA. Also, the use of dimensionless numbers is proposed to inform BPA analyses.
本文通过对比，突出了法医学中血痕形态分析（BPA）和物理科学中流体动力学（FD）这两个学科之间的关系。在 BPA 和 FD 两个领域中，科学家们都研究与空气或其他液体或固体接触的液体的运动和相变。本文讨论了与 FD 相关的五个 BPA 方面：作为流体的血液运动的物理力；液滴的产生；在空气中的飞行；对固体或液体表面的冲击；以及污迹的产生。对于这些主题中的每一个，都从 BPA 社区和 FD 社区的相关文献中进行了回顾。本文就联合开展 BPA 和 FD 研究的机会，以及开发基于 FD 的新工具和方法来支持 BPA 提出了评论意见。此外，本文还提出使用无量纲数来指导 BPA 分析。
