Abstract AR
هذا البحث دراسة حسابية قائمة على نظرية السريان المنفصل المتعدد الأطوار (نظرية لاجرانج) ؛ و بهدف متابعة و استنباط مسارات الجزئيات ذات الأبعاد بمقياس النانو و الممزوجة في سائل خلال سريانه حول مصفوفة من الألياف غير منتظمة و ذات أبعاد بمقياس الميكرو.
أظهرت النتائج التصاق بعض هذه الجزئيات على جدران الألياف مما قد يسب انسداد المسارات داخل المصفوفة.
لتلافى ذلك تم تفعيل دور الحمل القطعي المماسي (مارانجونى) مقترنا مع إحداث فرق في درجة الحرارة بين السائل و جدران ألياف المصفوفة.
Abstract EN
In the present work a numerical study based on discrete multiphase approach, Lagrangian approach, is proposed to investigate and predict the trajectories of nanoparticles-filled fluid (nanofluid) infiltrated around a staggered microfiber matrix.
The trajectory of the nanoparticle has been predicted by integrating the force balance on it in a Lagrangian reference frame during its motion through the fluid.
The governing integral equations for the conservation of mass, momentum and energy have been solved in a segregated numerical fashion by a Control- Volume-Based Finite-Element Method.
The nanoparticles trajectories and their interactions with fluid flow and microfiber walls have been predicted showing undesirable sticking tendency of the nanoparticles on the microfiber walls.
To avoid this tendency, the contribution of Marangoni shear stress has been introduced coupled with a temperature difference between the fluid flow and the microfiber walls.
