description | Analysis of flow through the conical diffuser of an annular combustion systemis presented. The flow is assumed to be unsteady, quasi three dimensional,compressible and turbulent. A k-ε model was used to simulate turbulence.Several area ratios and divergence angles were tested until circulation tookplace. At this angle a snout was introduced to correct the flow. A control volumemethod was used to solve the differential equations of the flow to obtain velocityand pressure coefficient distributions. The numerical results show that the axialvelocity decreases with diffuser length for a certain divergence angle. But itincreases with angle of divergence for the same area ratio, while the radialcomponent of velocity was found to increase with both. It was proved that thesnout can correct the flow whenever circulation takes place. |
