Abstract AR
إن عملية تدفق الدم خلال تضيق الشريان المتناظر يعد واحد من أهم الظواهر التي تؤخذ بنظر الاعتبار خلال تصلب الشرايين.
و بما أن الدم يصنف من الموائع الغير نيوتينية لذلك تمت دراسة أنواع الموائع و تأثير خواص الدم الغير نيوتيني على درجة تضيق الشريان.
كتبت معادلة الجريان بصيغة المسار الدوامي و من تحليلها عدديا، تمت مقارنة بين المائع النيوتيني و الغير النيوتيني لسرع جريان و لزوجة و مديات رقم رينولد مختلفة.
لقد تبين إن خصائص الدم يجب أن تكون ضمن حدود محدودة لغرض منع حدوث حالة تصلب الشريان.
Abstract EN
The prediction of the blood flow through an axisymmetric arterial stenosis is one of the most important aspects to be considered during the Atherosclerosis.
Since the blood is specified as a non-Newtonian flow, therefore the effect of fluid types and effect of rheological properties of non-Newtonian fluid on the degree of stenosis have been studied.
The motion equations are written in vorticity-stream function formulation and solved numerically.
A comparison is made between a Newtonian and non-Newtonian fluid for blood flow at different velocities, viscosity and Reynolds number were solved also.
It is found that the properties of blood must be at a certain range to preventing atheroscirasis.
