Abstract : Numerical simulation of blunt end and bevel end coaxial nozzle jets for incompressible flow is carried out using
Detached Eddy Simulation (DES). Transient analysis is preformed for three velocity ratios 0.5, 1 and 2. The results obtained
by 45 deg bevel end nozzle have been validated and benchmarked with the experimental results carried out. Jets diffuse at a
faster rate in bevel end nozzle compared to blunt end due to higher shear between the shorter and longer edges of the nozzle
leading to flow instabilities in bevel end nozzle jets. Also jets continue to be in the form of lump for all velocity ratios in
blunt end nozzle whereas jets diffuse in bevel end nozzle. This diffusive behavior will be more effective in enhancing mixing
phenomena between the jets.
