Linearized instability sheet atomization
Nettet1. mar. 1999 · A mass averaged spray angle is calculated from the patternator data and used in some of the calculations. This new model is referred to as the Linearized Instability Sheet Atomization (LISA) model, and is a complete set of equations which provide the required boundary data for the multi-dimensional, transient code, KIVA-3V. NettetThe computational fluid dynamics (CFD) modeling is performed using a linearized instability sheet atomization (LISA) model and validated by the measured values of droplets size distribution at varied gas-to-liquid flow rate ratios (GLR).
