چکیده

هدف از این پژوهش، مدل‌سازی هدایت حرارتی کامپوزیت پایه پلی‌اتیلن تقویت‌شده با نانولوله‌های کربنی هلیکال با روش اجزامحدود می‌باشد. نانولوله‌های کربنی هلیکال بشکل تصادفی با توزیع یکنواخت بانسبت منظری‌، درصد حجمی، شکل‌‌ها و جهت‌گیری‌های مختلف توسط کد پایتون با استفاده الگوریتم مونته‌کارلو در آباکوس ایجاد شدند. نتایج نشان می‌دهد که با افزایش درصد حجمی، نسبت منظری و شعاع نانوذرات هلیکال، مقدار ضریب رسانش حرارتی افزایش می‌یابد که این افزایش برای درصد حجمی 71/0 %، به مقدار 35/9 % بیشترین عامل تاثیرگذار و برای قطر نانولوله کربنی هلیکال با مقدار 1% افزایش در ضریب رسانش حرارتی نانوکامپوزیت، کمترین تاثیر را دارد.
