SummaryDescribe the proposed research in about 200 words.It is now widely believed that arterial fluid dynamics plays a crucial role in the initiation and development of atherosclen an arterial disease particularly prevalent in the coronary arteries. These arteries, situated on the surface of the be, heart, are unique in that their geometry varies substantially with time as the heart beats. Experimental measuremen coronary artery curvature and torsion show that the curvature variations are of the same order as the average curv-c and the torsion variations are large compared with the average torsion, and none of these quantities is asymptoti small. This prompts the question of whether the motion of the coronary arteries is a risk factor for atherosclerosis.Previous studies have considered flows in pipes (zero torsion) in which the curvature and its time-dependent variatiol asymptotically small. The research proposed here will develop and implement a numerical code to examine flows in f with general time-dependent curvature, and will accordingly break new ground in our understanding of flows in pipes time-dependent geometries. The implication of these results for atherosclerosis will also be assessed.
