Numerical Simulations of Fuel Droplet Flows Using a Lagrangian Triangular Mesh

摘要

This report describes work done to convert the incompressible, Lagrangian, triangular grid code, SPLISH, to the study of flows in and about fuel droplets. This has involved developing, testing and incorporating new algorithms for surface tension and viscosity. The major features of the Lagrangian method and the new algorithms are described. Benchmarks of the new algorithms are given. Several calculations are presented for kerosene droplets in air. Finally, extensions which make the code compressible and three dimensional are discussed.
