 umerical investigation of blood flows with slip boundary conditions</a>\nb

 ečas Seminar on Continuum Mechanics\n\nLecture held in Room K3\,  Faculty
  of Mathematics and Physics\, Charles University\, Sokolovská 83  Prague 
 8..\n\nAbstract\nMost studies of patient-specific blood flow models prescr
 ibe a no-slip boundary condition at the walls. Although its implementation
  is straightforward\, its validity at the blood-vessel wall interface is q
 uestionable. It has been suggested in (Nubar\, 1971) for example\, that a 
 slip boundary condition can be considered for blood flow in certain situat
 ions. We will discuss some effects of prescribing the Navier-type slip bou
 ndary condition\, which assumes a linear proportionality between the tange
 ntial part of the wall velocity and the shear stress using an additional p
 arameter. Given some measured flow data\, for example modern 4D-PC MRI ima
 ge\, we use variational data assimilation approach to estimate the Navier'
 s slip parameter on the wall for real data.\n
