Structural optimization of the air-blast atomizer based on three-dimensional simulation techniques

The experience gained in structural modifying the low-pressure drop gas turbine engine fuel atomizer with two air nozzles is presented. The volume of fluid (VOF) approach is used for analyzing the two-phase flows to describe the numerical analysis of atomization quality. The base design and the desi...

Description
Summary:	The experience gained in structural modifying the low-pressure drop gas turbine engine fuel atomizer with two air nozzles is presented. The volume of fluid (VOF) approach is used for analyzing the two-phase flows to describe the numerical analysis of atomization quality. The base design and the design based on numerical analysis are compared by using a full-scale experiment.
