The modified RNG k-ε model effectively improves the numerical prediction accuracy of blood flow affected by wall curvature effects, which may aid in computational fluid dynamics studies of arterial thrombosis.
May aid CFD thrombosis modeling; leaves open human validation before any practice impact.
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.
