Pemodelan Matematika Perpindahan Panas pada Stenosis Arteri Karotis

Carotid artery stenosis is the narrowing of the lumen (inner surface) of the carotid artery. Usually stenosis is caused by atherosclerosis, which is an atheromatose plaque due to inflammation consisting of necrotics, fats and cholesterol crystals. Occlusion of arterial lumens makes the brain lack blood supply causing damage to brain function. Sometimes, a long period of blood supply can cause permanent damage to vascular tissue in the brain. Stenosis also poses a dangerous threat to health, namely stroke. Narrowed carotid arteries have a certain temperature. The emergence of mathematical modeling as a new science is one alternative to solving this problem. By mathematical modeling, researchers obtained a formula that describes the state of heat transfer in the carotid artery according to the actual conditions regardless of the important factors in the system. In this study, a mathematical model was built on the above problem to analyze heat transfer that occurs in the carotid artery due to stenosis.   Keywords: Carotid artery stenosis, Mathematical modeling, Finite element
