Abstract
The blood viscosity is correlated with the risk of developing atherosclerotic lesions. The environmental factor can play an important role in altering hemodynamics and low-density lipoprotein (LDL) especially the ambient temperature. The greenhouse gas emission from energy or power production can increase the ambient temperature. This study investigated the effect of temperature-dependent blood viscosity on the LDL transport within the axisymmetric artery with a 40% stenosis blockage via computational fluid dynamics simulation. The results showed that the changing of blood viscosity inducing the change in pressure drop. The penetration locations of the LDL were also shifted which increased the risk of having LDL penetrating into the arterial wall. In addition, the outcome will contribute to the initial development of atherosclerosis modelling.
