الملخص

تستعرض هذه الدراسة كيفية تأثير هندسة المسام والمسامية على التوصيل الحراري وخصائص نقل الحرارة في السيليكون المسامي، باستخدام أداة "أوبن بي تي إي"، وهي أداة حسابية مفتوحة المصدر تعتمد على معادلة بولتزمان للنقل. قمنا بدراسة ثلاث أشكال هندسية للمسام (دائرية، مستطيلة وسداسية) مع نسب مسامية من 5% إلى 45% لدراسة تأثيرها على النقل الحراري الذي يتم بواسطة الفونونات. أظهرت النتائج علاقة واضحة بين التوصيل الحراري وشكل المسام ونسبة المسامية، إذ سجلت المسام ذات الشكل المستطيل أعلى قيم للتوصيل الحراري التي تتراوح من 64.4 واط/(متر•كلفن) عند نسبة 5% من المسامية إلى 26.7 واط/(متر•كلفن) عند نسبة 45% من المسامية. بينما أعطت للمسام الدائرية قيما متوسطة للتوصيل الحراري، تتراوح من 56.8 واط/(متر•كلفن) عند نسبة 5% من المسامية إلى 9.5 واط/(متر•كلفن) عند نسبة 45% من المسامية. أما بالنسبة للمسام السداسية فقد حققت أدنى قيم للتوصيل الحراري، حيث تراوحت بين 54.6 واط/(متر•كلفن) عند نسبة 5% من المسامية إلى 7.2 واط/(متر•كلفن) عند نسبة 45% من المسامية.
