الملخص
في هذه الدراسة ، تم تطبيق تقنية التذبذب في مبادل حراري متعدد الأنابيب مع وجود حواجز. تم فحص رقم Nusselts الخاص بالانتقال الحراري في المبادل الحراري (HE) على مدى واسع من ظروف التشغيل ، ورقم رينولدز (Re = 200-3000) ورقم رينولدز المتذبذب (Reo = 0-3800). أظهرت النتائج تحسنًا معنويًا في رقم نسلت على جانب الأنبوب. تم تحقيق 5 أضعاف من تحسين نقل الحرارة عند الحد الأقصى للتذبذب ومعدلات التدفق ، والحد الأقصى Nu = 180 عند Re = 1500 و Reo = 3800. كان لمعدل التدفق تأثير أكبر على تحسين نقل الحرارة من التدفق التذبذب عند Re> 1000. كما تم تقييم الأداء الحراري للمبادل الحراري TH. انخفض TH مع زيادة معدل التدفق والتدفق التذبذب بسبب الزيادة في P نتيجة لزيادة كثافة الخلط. 4.5 هي أعلى قيمة للأداء الحراري تم تحقيقها عند Re = 200 ، Reo = 1500
