DPM功能詢問(particle rotation & random eddy life time)

[luna6362]

大家好，我現在正在模擬一個壓縮機，裡面有一個用mrf方法旋轉的轉子，我想模擬油粒子在壓縮機內的逃脫狀況。

但我不確定我需不需要用到particle rotation & random eddy life time這兩個功能？

Hello everyone, I am currently simulating a compressor with a rotor rotating using the mrf method. I want to simulate the escape of oil particles in the compressor. But I’m not sure whether I need to use the particle rotation & random eddy life time functions?

Hello, those are extra particle physics and you can include them if you see fit. Have eddy lifetime model if you want your oil particles to interact with the continous phase's turbulence, have particle rotation if the particles are big and if you want to account for the rotational inertia..
