ABSTRACT
In order to investigate the application of lattice Boltzmann method (LBM) in the numerical simulation of computed tomography angiography-derived fractional flow reserve (FFR ), an idealized narrowed tube model and two coronary stenosis arterymodels are studied. Based on the open source code library (Palabos), the relative algorithm program in the development environment (Codeblocks) was improved. Through comparing and analyzing the results of FFR which is simulated by LBM and finite element analysis software ANSYS, and the feasibility of the numerical simulation of FFR by LBM was verified . The results show that the relative error between the results of LBM and finite element analysis software ANSYS is about 1%, which vertifies the feasibility of simulating the coronary FFR by LBM. The simulation of this study provides technical support for developing future FFR application software, and lays the foundation for the calculation of clinical FFR .
