المركبات غير الحرجة لأشرطة السوائل الرقيقة للمزيج الثنائي
محتوى المقالة الرئيسي
الملخص
تركز هذه الدراسة على الحلول غير الخطية لأشرطة مقيدة من خليط ثنائي ذو سطح حر ، موضوع على سطح صلب محايد طاقياً وتخضع لشروط حدودية دورية على الجدران الجانبية. يتم استخدام نموذج كان-هيليارد في حدوده الثابتة لاستكشاف المسألة، ويعتبر السطح الحر حادًا بتوتر سطحه. يُسمح للواجهات الداخلية بين البوليمراين بالانتشار. تتم دراسة المشكلة من خلال التفرعات المتغيرة لعدة بارامترات، على وجه الخصوص توتر السطح وحجم مجال الشريط الجانبي، وسمك الشريط المتوسط للتراكيب المتجانسة والتي تتكون من طبقتين متجانستين جانبيًا (أفقيًا وعرضيًا). يُعتبر الخليط في تركيبة غير حرجة بقيمة . تكشف النتائج عن مجموعة كبيرة من الحلول، توفر رؤى قيمة حول الخصائص الهيكلية لأشرطة السوائل الرقيقة من خليط ثنائي.
