ABSTRACT

The unsteady blood flow in the stenosed porous artery subjected to a magnetic field was studied analytically. Oscillating pressure gradient and periodic body acceleration were imposed on the flow field. The effects of the magnetic field and the permeability of the stenosed artery on the blood velocity were studied. The results showed that the magnetic field affected the flow field significantly which can be beneficial for some practical problems.

 

Keywords: Magnetic field; porous medium; stenosed artery; unsteady blood flow

 

ABSTRAK

Aliran darah yang tidak stabil di dalam arteri berliang tersumbat yang dikenakan medan magnet dikaji secara beranalisis. Kecerunan tekanan berayun dan pecutan badan berkala telah dikenakan ke atas medan aliran. Kesan medan magnet dan arteri tersumbat pada halaju darah telah dikaji. Keputusan menunjukkan bahawa medan magnet mempengaruhi aliran dengan ketara yang bermanfaat untuk beberapa masalah sebenar.

 

Kata kunci: Aliran darah tak mantap; arteri stenosis; medan magnet; medium berliang
