Manyetik alan, kanala akış yönüne dik olarak uygulanmıştır. Re=2250 ve manyetik alan kuvveti sırasıyla 0T, 0.04T, 0.08T ve 0.12T olarak seçilmiştir. Bunun yanında, akışkan sıcaklığı 473.15 K iken cidar sıcaklığı 373.15 K’dir. Hesaplamalar ANSYS-Fluent ticari yazılımı ile gerçekleştirilmiştir. Manyetik alanın akışkan hızı, basınç ve sıcaklık üzerindeki etkileri grafiksel olarak sunulmuştur. Manyetik alan etkisinin akışkan hızını azaltırken, basıncı arttırdığı gözlemlenmiştir. Ayrıca, manyetik alan boru uzunluğu boyunca kanalın farklı bölgelerinde, sıcaklığı farklı şekilde etkilediği gözlemlenmiştir.
