Application of Computational Physics: Blood Vessel Constrictions and Medical Infuses

摘要

Application of computation in many fields are growing fast in last twodecades. Increasing on computation performance helps researchers to understandnatural phenomena in many fields of science and technology including in lifesciences. Computational fluid dynamic is one of numerical methods which is verypopular used to describe those phenomena. In this paper we propose movingparticle semi-implicit (MPS) and molecular dynamics (MD) to describe differentphenomena in blood vessel. The effect of increasing the blood pressure onvessel wall will be calculate using MD methods, while the two fluid blendingdynamics will be discussed using MPS. Result from the first phenomenon showsthat around 80% of constriction on blood vessel make blood vessel increase andwill start to leak on vessel wall, while from the second phenomenon the resultshows the visualization of two fluids mixture (drugs and blood) influenced byratio of drugs debit to blood debit. Keywords: molecular dynamic, blood vessel, fluid dynamic, moving particlesemi implicit.
