The modified RNG k-ε model in bend can effectively improve the blood flow's numerical prediction accuracy affected by wall curvature effect, laying the foundation for further research on blood flow in bend.
The numerical simulation model of blood flow in bend is studied in this paper. The curvature modification is conducted for the blood flow model in bend to obtain the modified blood flow model in bend. The modified model is verified by U tube. By comparing the simulation results with the experimental results obtained by measuring the flow data in U tube, it was found that the modified blood flow model in bend can effectively improve the prediction accuracy of blood flow data affected by the curvature effect.
