Research on Efficiency Improvement of CFD Computation Based on Cluster Analysis

Abstract

The paper involves an improved vector field clustering algorithm, which has achieved good performance when incorporated into the analysis of vector field. Additionally, a weighted K-means algorithm is presented, which is more appropriate for the analysis of scalar field clustering. The improved algorithm has better clustering results on the scalar field, which are more consistent with the physical laws by comparison. Ultimately, the algorithm is put in use for the CFD calculation. The number of iterations is decreased and the convergence speed is accelerated after the clustering algorithm is adopted for better initial condition.
