Rheolojik özellikli manyetik sıvıların elektromanyetik alandaki davranışlarının analizi

Bu makalede, rheolojik özellikleri power law akış modeliyle belirlenen bir manyetik sıvının homojen olmayan manyetik alana yerleştirilen iki plaka arasındaki akışı incelenmiştir. Manyetik sıvının hızının ve kalınlığının analitik ifadeleri sistem parametrelerine bağlı olarak elde edilmiştir. Elde edilen denklemler endüstrideki teknolojik sistemlerde kullanılan manyetik sıvılar için kullanılabilecek uygunluktadırlar.

Analysis of the behavior of the magnetic liquids with rheologic property in the electromagnetic field

In this paper, flow of a magnetic liquid whose rheologie properties are determined with power law is investigated between two plates in the non-homogenous magnetic field. Analytical equations of the speed and thickness of the magnetic liquid are obtained as depending on the system parameters. The obtained equations are suitable for the magnetic liquids used in the technological systems in industry.
