Hi, I am simulating a INSEAN E779A propeller using Fluent. I have created unstructured mesh in ICEM. My problem is I am getting very low value of thrust compared to experimental results? Can anyone suggest the reason for that?
Thanks Gaurav |

First things first.
I would check and double check the angular velocity of the blade, density of the fluid and your geometry...happy digging. |

I have provided the fluid with rotating reference frame. So I need not to give angular velocity to blade. Density of water is 1000 kg/m^3, that I have checked, that is not much different from experiment.
