description |
A new generation of aerosol technology are expand rapidly where the
research and development are focused on the analysis of propellants, packaging and
ingredients to make the aerosol has a high performance product. However, there are
a few main problems with pressurised aerosol spray, which are the production of
VOC and the quality of spraying process. Therefore, in this study the development of
an internal nozzle has been investigated to analyse the characterictics of spray by
using CFD simulation. The analysis is focused on various pressure supply up to
9bar, where the n-butane and water are applied as a liquid phases material. The
simulation is done based on two types of selected nozzle design. The result shows
that, the values of velocity, TKE and Reynolds Number for both liquid phases are
increase when the pressure supply increased. It was observed that, when comparing
the two type of nozzle design, it shown that the value of velocity and Reynolds
number is relatively similar for both liquid phases, while the TKE value is more
difference due to the material properties and nozzle design. Therefore, the use of
water is acceptable as an alternative to substitute the n-butane liquid phase in
producing an aerosol spray product. |
