Abstract AR
فی هذا البحث یتم دراسة تأثیر إدماج شبكة نحاسیة علی مبادل حراری تحت ظروف سریان ثابت صفائحی.
و من اجل ذلك تم عمل نموذج ثلاثی الإبعاد للمبادل الحراری.
قطر سلك الشبكة النحاسیة ( ٥، ۲) مم و المسامیة تساوی ( ٧٥، ۰) و نفاذیة تساوی (۱۰-۱۰) متر۲ و التباعد بین طبقات الشبكة النحاسیة یتراوح من( ۳) إلى (۲٥) مم.
یسری الهواء بسرعة أقصاها ( ٥، ۳) سمثانیة خلال مسار ( ٥۰ سم في ۲٥ سم) بدرجة حرارة ۲٥ درجة مئویة بینما تسری المیاه داخل أنبوبة معرجة ( ۱۹ ) مم بسرعة ( ۱) مترثانیة بدرجة حرارة (٥۰) درجة مئویة.
تم تقییم الأداء الحراری و الهیدرولكی و أظهرت النتائج تحسین یصل إلی( ۲٥۰) % في معامل انتقال الحرارة الكلی للشبكة النحاسیة ذات التباعد ۳ مم.
Abstract EN
In this paper, the insertion effect of a woven wire mesh to cross flow heat exchanger will be studied under steady state laminar flow conditions.
3-D numerical model was developed for the bare heat exchanger and the other wire mesh modules.
The mesh wire diameter is 2.5 mm, porosity of 0.75, permeability of 10-10 and layer-to-layer spacings of (3, 5, 10, 15, 20 and 25 mm).
Air flows with velocity range up to 3.5 cm/s through rectangular duct of 50 cm X 25 cm with inlet temperature of 25oC before it is heated with corrugated water tube (19 mm in diameter) with hot water inlet velocity of 1 m/s and temperature of 50 oC.
The thermal and hydraulic performance were evaluated.
Results showed that an enhancement in overall heat transfer coefficient was achieved of 250 % for the 3 mm spaced module while the air pressure drop increases significantly.
