抄録(英) | Diesel engines as power sources ranging in size from small to large have been extensively used worldwide. However, further improvement in the complicated urea-SCR systems is required to meet the stricter NOx regulations on exhaust gas. This study shows that the behavior of the entire gas/injected droplet can be verified using visualization equipment. Valuable gas-liquid multiphase flow PIV results using the DDM were obtained. In addition, the detachment droplet behavior from the liquid film was visualized as unknown droplet behavior. These validations are considered to be useful for establishing the PIV-DDM for the flow characteristic estimation in the exhaust pipe of the urea-SCR system. 翻訳 |
