Numerical simulation of extracorporeal membrane oxygenators to investigate important parameters and membrane thickness in oxygen exchange rate

Behnam Dilmaghani Hassanlouei; Nader Pourmahmoud; Pierre Sullivan

Volume 13, Issue 1 , September 2023, Pages 1-12


  In this article, an extracorporeal membrane oxygenator (ECMO) is simulated in 2D geometry using computational fluid dynamics (CFD). Momentum and mass transport equations were solved for the laminar flow regime (30 < Re < 130 for the blood channel) using the finite element method. In this study, ...  Read More
