  where:
  * C is concentration
  * D is the diffusion coefficient
  * V is the velocity of flow
  * x is the distance down the channel
  * γ is the wall shear rate
  * b is the height of the channel
  This equation  is especially applicable to analyzing protein adsorption to biomedical devices in arteries, e.g. stents.
