تجد عملية النفث الهوائي تطبيقات في مجالات الهندسة مثل لحام التدفق العكسي، وتجفيف النسيج، وتبريد شفرات وطواقم احتراق الغاز التوربيني. تم تطوير منصة تجريبية لدراسة تأثير تقنيات الاختبار ووسائل القياس على خصائص نقل الحرارة التوافقية لتجميعات النفث الهوائي المتغيرة. تتضمن التجربة استخدام أهداف مسخنة مصنوعة من رقائق فولاذية من الستانلس ستيل رقيقة بظروف حدودية لتدفق الحرارة ثابتة. يتم قياس حقول درجات حرارة سطح الهدف باستخدام تقنيات الحرارة والحركية، بينما يتم تقييم تأثير ظاهرة التدفق المتقاطع في الممر الداخلي للقسم التجريبي على خصائص نقل الحرارة التوافقية عن طريق تغيير إعدادات التدفق الخارجي. يُمثِّل المخرج الواحد مستوى تدفق متقاطع قوي والمخرج المزدوج يُمثِّل مستوى تدفق متقاطع معتدل. يتم اعتبار صفيفين من فوهات النفث، مرتبطة في خط ومنفصلة، في هذا العمل التجريبي؛ يتكون كل صف من 44 فوهة للنفث من 4 صفوف، ولكل صف 11 ثقوب نفث. يتم تقديم الأعداد اللوكالية والمكانية لنوسلت كوسيلت في الوقت الغير ثابت كدالة لعدد رينولدز النفث، مع تأثرها بقطر فوهة النفث. يؤثر مستوى التدفق المتقاطع بشكل كبير على الأعداد اللوكالية والمكانية لنوسلت في كلا القيم المحلية والمتوسطة في اتجاه الطول، بغض النظر عن عدد رينولدز الذي تمت دراسته. يُلاحظ أنه عند مقارنة النتائج الحالية مع الأعمال السابقة، تحقق الاتفاق عند استخدام تقنيات تجريبية مماثلة، بينما تنشأ عدم التطابق عند استخدام تقنيات تجريبية مختلفة، مما يُسلط الضوء على الدور الحاسم للتقنية التجريبية في تقييم خصائص نقل الحرارة.
