Simulation Non-Newtonian blood flow behavior in Abaqus CFD

In this tutorial, the Simulation Non-Newtonian blood flow behavior in Abaqus CFD has been investigated. The blood solid part can be created in Abaqus or it can be imported as a CAD part to the Abaqus CFD. The blood part has one inlet flow and outlets zone that you can see the assembled part below

The default model for the blood in Abaqus CFD is Newtonian model and to create Non-Newtonian model, Carreau-Yasuda viscosity model is selected.This model has been successful in representing the shear-thinning behavior of blood. Blood is a complex biological fluid and has elements in its composition, such as erythrocytes, which give it a non-Newtonian behavior. Typically, when carotid blood flow is studied, this aspect is frequently ignored and blood is modeled as a Newtonian fluid, with constant viscosity. The Carreau-Yasuda model is not available in Abaqus cae and it needs some modification in the edit keyboard file. The flow step with laminar for the flow type regime is selected. The inlet boundary condition as inlet velocity is assigned to the entrance zone. Two outlet boundary as pressure condition as selected for two outlet zones. Wall boundary condition is also assigned to the outer surfaces and shear wall outputs is requested for it. The mesh should be fine to obtain correct results

After the simulation, all results such as pressure, velocity, velocity vector, diagrams, and … are achievable. You can see some figures for the results below

You can provide CAE ,INP,and English video files of this simulation here. The cost of these files is Twenty-One Euros. you can click on the bellow bottom to beginning process
