Abstract AR
في هذا البحث نتناول تحليل الجريان اللامستقر لمائع لا نيوتيني في أنبوب منحنى ذو مقطع مستطيل الشكل.لقد بينا أن ثلاثة أعداد لا بعدية تتحكم بمعادلات الحركة و هي, عددين, العدد اللانيوتيني و متغير التكرار .استخدمت طريقة تكرارية لحل معادلات الحركة (كالريكن).
قدمنا دراسة تحليلية لتأثير الأعداد الأنفة الذكر على كل من الحركة الثانوية و السرعة المحورية.
Abstract EN
This study is concerned with the unsteady flow of non-Newtonian, viscous, incompressible fluid in a curved pipe with rectangular cross-section, under the action of pressure gradient.
An orthogonal coordinate system has been used to describe the fluid motion and it is found that the motion equations are controlled by three parameters namely; Dean number, non-Newtonian parameter and frequency parameter.
Solution for the secondary flow and the axial velocity are droved as perturbation over straight pipe.
Firstly the expansion was in terms of Dean number and secondly in terms of frequency parameter.
Perturbation equations are solved by using variation method namely, Galerkin's method, after eliminating the dependency on time.
The solutions have been developed in Cartesian coordinate for harmonic and biharmonic equations.
The effect of the non-dimensional parameters mentioned above on the secondary flow, the axial velocity and the flow in the centre plane is considered.
In this study we covered the steady state under consideration.
