چکیده
We present a new numerical simulation framework for prediction of flow patterns in the human left ventricle model. In this study, radial basis function (RBF) mesh morphing method is developed and applied within finite-volume computational fluid dynamics (CFD) approach. The simulations are designed to closely mimic details recent tomographic particle image velocimetry (TomoPIV) experiments. numerically simulated dynamic motions tri-leaflet biological mitral valve emulated through RBF method. arbitrary Lagrangian-Eulerian (ALE) based CFD performed with RBF-defined deforming wall boundaries. results obtained show good agreement experiments, confirming reliability accuracy framework. • novel approach on function. model simulated. A between experiments (Tomo PIV).

Evaluation of diastolic blood flow dynamic of the left ventricle in dogs with mitral valve regurgitation using vector flow mapping
Mitral valve regurgitation (MVR) is a common valvular disease in dogs. Hydrokinetic evaluation of the blood flow within the ventricles has become possible by vector flow mapping (VFM), which shows the blood flow within the ventricles in vector and vortex flows. Blood flow within the left ventricle of MVR dogs was compared at different stages of MVR and to that of normal dogs. 14 normal dogs and...
متن کاملNovel Radial Basis Function Neural Networks based on Probabilistic Evolutionary and Gaussian Mixture Model for Satellites Optimum Selection
In this study, two novel learning algorithms have been applied on Radial Basis Function Neural Network (RBFNN) to approximate the functions with high non-linear order. The Probabilistic Evolutionary (PE) and Gaussian Mixture Model (GMM) techniques are proposed to significantly minimize the error functions. The main idea is concerning the various strategies to optimize the procedure of Gradient ...
