[ 1 ] - بررسی تأثیر درون‌لوله‌ایستاره‌ای روی عملکرد حرارتی آبگرمکن گازی در جریان مغشوش

In this work, the effects of star tube insert as one of the best passive method for enhancement heat transfer in gas water heater are studied. The effects of this tube insert with step 2, 3 and 4.5 cm on flow characteristics and thermal performance of the gas water heater are investigated using finite volume method. In the cases studied (Reynolds numbers between 5800 and 18600), Nu Number is ob...
