Computational prediction of blood damage has become a crucial tool for evaluating blood-wetted medical devices and pathological hemodynamics. A difficulty arises in predicting blood damage under turbulent flow conditions because the total stress is indeterminate. Common practice uses the Reynolds stress as an estimation of the total stress causing damage to the blood cells. This study investigates the error introduced by making this substitution, and further shows that energy dissipation is a more appropriate metric of blood trauma.

关于计算血液损伤的湍流应力的表示。

血液损伤的计算预测已成为评估血湿医疗器械和病理血流动力学的重要工具。由于总应力不确定，因此很难预测湍流条件下的血液损伤。通常的做法是使用雷诺应力来估计对血细胞造成损害的总应力。本研究调查了进行这种替换所引入的误差，并进一步表明能量耗散是更合适的血液创伤指标。
