对固体颗粒在热等离子体流中的烧蚀过程进行了数值模拟。该模型基于约束插值迭代-联合统一过程（CIP-CUP）方法，可以模拟不可压缩流和可压缩流，进而模拟多相流。此外，体积分数（VOF）功能被引入到烧蚀过程中跟踪的固体表面。利用该模型，模拟了聚乙烯粒子在热等离子体流中的烧蚀过程。结果表明，烧蚀发生更强烈的颗粒的上游表面，从而产生强大的气流。© 2009日本电气工程师协会。出版社：John Wiley & Sons，Inc.
Numerical modeling was performed for ablation processing of a solid particle in a thermal plasma flow. The model is based on Constrained Interpolation Propagation–Combined and Unified Procedure (CIP–CUP) method, which can simulate incompressible and compressible flows and then the multiphase flow. Furthermore, the volume of fraction (VOF) function was introduced to track the surface of the solid during ablation. Using that developed model, the ablation process of a polyethylene particle was simulated in a thermal plasma flow. Results show that ablation occurs more strongly at the particle's upstream surface, thereby producing strong gas flow. © 2009 Institute of Electrical Engineers of Japan.
