Phân tích hành vi của nanofluid lai trong một khoang xốp kèm theo tác động của lực Lorentz và bức xạ
Tóm tắt
Chúng tôi nghiên cứu quá trình vận chuyển đối lưu của nanofluid lai trong một môi trường có khả năng thấm với sự xuất hiện của lực từ bên ngoài bằng cách mô hình hóa nó qua phương pháp phần tử hữu hạn dựa trên khối điều khiển. Để áp dụng các thuật ngữ ảnh hưởng của độ thấm, một thuật ngữ đã được thêm vào động lượng và bức xạ được tham gia để thể hiện các trạng thái khác nhau của các hạt nano. Tác động của các tham số Darcy và Rayleigh cũng như tham số từ trường và bức xạ đối với hiệu suất của nanofluid được nghiên cứu và trình bày. Chúng tôi quan sát thấy rằng chế độ dẫn nhiệt tăng cường với các giá trị Ha cao hơn. Số Nusselt Nu tăng lên khi đưa vào thuật ngữ nguồn bức xạ. Việc bổ sung lực Lorentz làm cho chế độ dẫn nhiệt trở nên nhạy cảm hơn. Sự đồng nhất với các kết quả đã được công bố khiến chúng tôi tự tin hơn về tính hợp lệ của các phép tính số học của chúng tôi.
