Abstract:
This paper reviews progress achieved by incorporating principles of fluid dynamics into BPA efforts in order to facilitate more supportive forensic investigations. A new technique for reconstructing blood spatter trajectories accounting for features due to gravity and air drag is particularly examined here. Changes in the impact angle of stains are studied more thoroughly, as these changes may reflect in the expansion around the area of origin, especially for stained samples that entered from top downwards. A comparative analysis of new backward spatter models shows they work well in generating the features of bloodstains related to gunshot wounds, linking physical processes with observable patterns. Another development includes the quantitative distinction of contact transfer over against spatter stains through microscopic examination, in which partial observer bias might be minimized. The study points to the contextual influence on the analyst's decisions, and it also raises the point that surface coatings have a strong impact on the morphological features of bloodstains. The last part of the study focuses on the dried blood pattern formation: its implications regarding diagnostic approaches associated with diseases and ailments. This work represents, in itself, the interdisciplinary nature behind BPA and fluid dynamics, a field that shall open ways for further research and improve forensic methodologies.
