Abstract AR

يتضمن البحث الحالي إجراء دراسة عددية لتوليد الانتروبي خلال قناة مربعة عمودية مملوءة بوسط مسامي مشبع و معرضة إلى ظروف حدية حرارية ثابتة الحرارة و مختلفة على جانبي القناة الأيمن و الأيسر.

تم دراسة تأثير الأرقام على توليد الانتروبي خلال القناة المسامية.

من نتائج البحث تبين أن توليد الانتروبي يتناسب عكسيا مع رقمي (Reynold and Darcy) و يتناسب طرديا مع رقم (Eckert).

من النتائج يتبين تناقص رقم (BEJAN) بزيادة رقمي (REYNOLD AND DARCY ) أي ان الاارجاعية نتيجة احتكاك المائع هي السائدة في حقل الجريان.

في حين عند زيادة رقم (ECKRET) فأن الاارجاعية نتيجة انتقال الحرارة هي السائدة.

Abstract EN

Entropy generation in a vertical square channel packed with saturated porous media, and subjected to differentially heated isothermal walls has been numerically investigated.

The effect of Darcy, Reynolds, and Eckert numbers on Entropy generation was studied.

The entropy generation was found to be inversely proportional to both Reynolds and Darcy number, while it was directly proportional with the Eckert number.

It was shown that as Darcy and Reynolds numbers were increasing, the Bejan number decreases, i.e., the irreversibility due fluid friction is dominated, while as the Eckert increases, theirreversibility due to heat transfer increases.
