title: Computational analysis of magnetic effects on pulsatile flow of couple stress fluid through a bifurcated artery.
abstract: OBJECTIVE
  The objective of the present study is to investigate the magnetic field effect on pulsatile flow of blood through a bifurcated artery with mild stenosis in its parent lumen by taking blood as couple stress fluid.
  
  
  METHODS
  The equations governing the flow are made non-dimensional, and coordinate transformation is employed to convert the irregular boundary to a regular boundary. The resulting system of equations is solved numerically using the finite difference method.
  
  
  RESULTS
  The shear stress, flow rate and impedance near the apex with pertinent parameters are obtained numerically and analyzed graphically.
  
  
  CONCLUSIONS
  It is noticed that physical quantities are changing suddenly with all parameters on both sides of the apex. This occurs because of back flow of the streaming blood at the onset of the lateral junction and secondary flow near the apex in the daughter artery.
