Nano-bubbles in blood flow Simulation in Ansys Fluent

Nano-bubbles in blood flow play an important role in biomedical applications such as targeted drug delivery and diagnostic imaging. In this study, we carried out a numerical investigation of nano-bubble transport in a bifurcated artery using ANSYS. Blood was modeled as a non-Newtonian fluid with the Carreau–Yasuda model, while nano-bubbles were introduced as a passive scalar phase at physiologically relevant concentrations.

Two cases were simulated: one with blood flow alone and another with nano-bubbles suspended in the flow. The results capture pressure, velocity, and wall shear stress distributions, along with bubble concentration fields and pathlines. The comparison between the two cases highlights the influence of nano-bubbles on local hemodynamics and stress patterns.

The simulations demonstrates how computational modeling can provide insight into complex biofluid systems, offering valuable understanding for future biomedical and therapeutic applications.
