Improvement of Hybrid Scheme for WAVE-MTAB Model and Analytical Study of Diesel Spray Using Theory on the Spray Similarity

摘要

In order to further improve the thermal efficiency of diesel engines, this report focuses on the influence of injection condition on similarity of similar spray. To accurately reproduce the diesel spray in our laboratory, the WAVE-MTAB model was developed, and improvements were made to switch between two breakup models. As a result, switching of the breakup model can be done according to the physical phenomenon, and it is considered that similar spray can be reproduced generally well when using theory on the spray similarity.
