Air core diameter, spray cone angle and spray breakup length of simplex atomizer with various exit orifice diameters and Reynolds numbers / Muhd Sulhan Abdul Kadir

Simplex atomizer is the simplest form of swirl atomizer. The principal function of the atomizer is to break the liquid into very small droplets. It became challenging to designing the atomizer due to vary application and performance characteristics in wide range of industries. It require an understa...
