Abstract
Recently-developed computer graphic techniques are being applied to certain hemo-dynamic and rheologic problems. Involved are fluid dynamic concepts and numerical analysis techniques. One particular study concerns the simulation of blood flow through prosthetic heart valves in a desire to form an optimum flow design. The investigation has been enlarged to include the study of localisation factors involved in the development of atherosclerotic lesions. Two-dimensional semi-quantitative results showed turbulent motion at, sites of predilection for atherosclerotic plaques. This lends credence to thoughts of turbulence causing injury to the intima and subsequent lesion development. Also formed were preliminary motion studies of idealised heart valve occluders and such simulation compared favourably with clinical findings. These studies have led to shear stress evaluations and the representation of blood flow by particle motion.
