Technical Notes Characteristics of collision spray of fuel jet using Ringed impingement wall head

摘要

When the fuel jet collides with the ringed- impingement wall head, the penetration power is suppressed an the diffusivity of the spray becomes strong. If the groove is set in the inner wall of the ringed- Impingement wall head, the diffusivity of the spray Becomes strong, and deep grooves have effects on the Three-dimensional spray.
