CFD propeller problem
Hi
I am doing CFD analysis of a propeller. It is a steady state analysis hence i am using frame motion. I have created 2 domains, the static and rotating domains. This is the mesh i have created, https://drive.google.com/file/d/1ej6...ew?usp=sharing When i load this mesh into fluent, i get these messages, https://drive.google.com/file/d/16-y...ew?usp=sharing https://drive.google.com/file/d/1hCG...ew?usp=sharing What do these mean? How should i eliminate them? Also, when i check the velocity contours, i get these strange areas at the interface of the rotating and static domains which i think are because of the above messages. Am i wrong? Have a look at these images, https://drive.google.com/file/d/1noy...ew?usp=sharing https://drive.google.com/file/d/1lKn...ew?usp=sharing Lastly, the thrust value that i get is approximately 50% of the actual value. So there's a big error here. Please help me with this problem, i will be extremely grateful! Regards & Thanks |
