چکیده

مطالعه حاضر به شبیه سازی عددی جریان سیال نیوتنی و غیر نیوتنی درون لوله  اعوجاجی،مجهز به نوارهای پیچی معمولی شیاردار در شرط مرزی شار ثابت با استفاده از روش عددی حجم محدودپرداخته است .جهت اعتبار سنجی نتایج شبیه سازی عددی با نتایج با معادلات تجربی محققان دیگرمقایسه شده است. آب به عنوان سیال نیوتنی و کربوکسی میتل سلولز در آب به عنوان سیال غیر نیوتنی استفاده شده و محدوده تغییرات اعداد رینولدز برای سیالات به ترتیب در محدوده جریان درهم در نظر گرفته شده است. مطالعه فوق کاربرد مدل های مختلف درهمی جریان، اعمال شارهای حرارتی متغیر و نیز شیار روی نوار،بر روی عدد ناسلت و ضریب اصطکاک را نشان می‌دهد. نتایج نشان می‌دهد که استفاده از مدل استاندارد κ-ω در جریان درهم سیال نیوتنی، نسبت به مدل های دیگر مناسب بوده و نتایج به دست آمده تطابق خوبی با داده های تجربی داشته و متوسط اختلاف نتایج برای عدد ناسلت برای نوارپیچی ساده و شیاردار به ترتیب کمتر از ۲/ ۱۵ و ۴/ ۱۴ درصد خواهدبود .از طرفی برای سیال غیر نیوتنی با شرایط  یکسان ،استفاده از مدل κ-ε نسبت به مدل های دیگر مناسب تر است و متوسط مقدار اختلاف برای عدد ناسلت برای نوارپیچی ساده کمتر از ۱۰ درصد خواهدبود.

چکیده [English]

The aim of present paper is to study numerical simulation by using finite volume method for Newtonian and non-Newtonian fluid flow inside corrugated tube equipped with typical twisted tape and V-cut twisted tape at constant heat flux. For validation of this simulation, this results compared with empirical correlations of researchers. In this analysis water was as Newtonian fluid and 0.2 wt % carboxymethyle cellulse in water was as a non-Newtonian fluid, the range of Reynolds number for Newtonian and non-Newtonian fluid varied 5300 to 25700 and 2400 to 6800 respectively. In this analysis, the effects of using different turbulence models, variable heat flux and creating V-cut on Nusselt number and friction factor is investigated. The obtained results showed that standard κ -ω model of turbulence for Newtonian fluid is a proper model rather than the other models and it had good agreements between experimental data, and the average differences for Nusselt number in typical and V-cut twisted tapes were less than 15.2% and 14.4% respectively. On other hand, in identical condition for non-Newtonian fluid, using of standard κ - ε model of turbulence is a proper model rather than the other models and the average differences on Nusselt number for typical twisted tape were less than 18%..
