Abstract

Injecting liquid spray using a surface mounted swirl injector in a gas pipe flow to achieve a uniform mixture within a limited distance from the injector location is a challenging problem. The spatial distribution of liquid mass has to be directly related to the mass of gas distribution in the pipe. It is therefore necessary to be able to control the liquid mass spatial distribution within the gas pipe to have similar liquid to gas ratio throughout the pipe. This work analyzes the mass distribution from a swirl injector that has any nozzle cut profile. An equation has been derived to estimate the nozzle circumferential distribution of the mass relative to the total mass exiting the nozzle. The equation requires the nozzle flow angle and profile of the nozzle cut. The flow angle at the nozzle exit has been estimated using a CFD single phase calculations. The final results provide a guideline for the designer to the required nozzle cut profile to achieve a specific circumferential mass distribution. The expected spray shape based on the mass distribution exiting the nozzle has been similar to what has been shown from the
spray images. Further work will be carried out to optimize the nozzle cut for different gas flow profiles.
