Abstract:

Needle valve is the key component of diesel engine cylinder. Changing the nozzle Orifice chamferinging will influence the flow coefficient and spray performance. Firstly, we proposed a physical model of abrasive flow field inside the needle valve based on computational fluid dynamics technology. Then, we set the computing method and boundary type. Finally, we simulated the abrasive flow field using fluent software. The result is useful for guidance in the actual grinding process.
