Role Of Compressibility And Slip In Blood Flow Through A Local Constriction

One type of blood disease is a narrowing of a tubular structure, known as constriction or stenosis and high cholesterol is one of the main causes for this. Suitable mathematical models are important to describe this phenomenon, and to study the problem analytically and numerically. An approximate analytical solution and a recently developed particle-based method called multi-particle collision dynamics (MPC) is used to simulate the weakly compressible steady flow through a three-dimensional constricted axisymmetric cylinder. The particle collisions in
