Abstract : The effects of inserted needle on the subcutaneous interstitial flow is studied. A goal is to describe the physical stress affecting cells during acupuncture needling. The convective Brinkman equations are considered to describe the flow through a fibrous medium. Three-dimensional simulations are carried out employing an ALE finite element model. Numerical studies illustrate the acute physical stress developed by the implantation of a needle.
