A paper entitled “A numerical study on the flow of blood and the transport of LDL in the human aorta: the physiological significance of the helical flow in the aortic arch” by researchers from the School of Biological Science and Medical Engineering was published in American Journal of Physiology - Heart and Circulatory Physiology. This paper studies the transport pattern of low-density lipoproteins (LDLs) in the human aorta. Based on the numerical simulation results, it is proposed that the rotor flow in the arterial system can inhibit the deposition of harmful lipids (LDLs) in the vascular wall and other physiological functions, and the principle of the rotor flow can be used in the design of cardiovascular interventional therapy/apparatus.
