Hello, i have designed a cascade impactor. It's useful for separate particles from air.
I want to simulate the air with the particles, but i can't adjust the flow "box" (Image). How can I do it?
the size of the comp domain is automatically set to the size of your assembly for internal analysis
for external it is set based on some geometric properties but you can resize by editing the defintiion of the comp domain
You are right with this. I have the problem with a porous zone. I will discribe a little my piece.
It is like a pipe and inside it has some walls with little holes where the aire goes across. Crossing the holes and very near to theese, there is a surface i have put for imact the air there.
The problem is in the last stage, there is not a wall with holes. There is a wall with porous zone. And crossing this porous zone is the end of my pipe with an output.
The main thing is that solidworks detect this porous zones as a lid and define the domain until here, and I want a bigger domain, crossing the porous zone and going until the end.
hi, my suggestion is to start a bit simpler and add components and complexity and learn along the way
or if you can post your model, post it here as i'm not really following what problem you're having
Hello Jared, I upload my model here.
I explain my three problems:
3.The idea of the model is that the air go stage by stage into the diferent little holes, but i don't know why, the air goes across the edges as you can see in here:
Thank you a lot.
Is this a commercial or educational application?
This is the commetcial one.
are you trying to use a full license of flow simulatino or flow express?
also, didy ou notice in your assembly that many of your parts are surfaces only? they will not be recognized by flow simulation
but maybe i'm opening the wrong model? it looks nothing like the one that you posted
You are right. I am remodeling from the begining and testing from parts.
I am going to ask you a new thing.
I want to do a new parametric study. I want to fin the are of a surface depending on the total particles absorved or not. But when I want to add the goals, there appear no option about particles. Evereything is about the flow.
Is there any option i am missing?
i don't think you can optimize based on that parameter
not every parameter can be used for the goal seeking
thanks for all your answers. I think I have all of my model completed, by something rare happens to the particles. It is suposed that each of four diferent type of particles impact in one of the differents plates crossing the holes. The problem is that the particles doesn't arribe to crosse it.
I have a pump aspiring at the end of the model. I have put 2.3 m3/h for simulate this. But particles doesn't arribe. Do you know which may be the problem?
I upload here my model again.
your default wall condition is absorption, so i think your particles get launched and then absorbed on those w alls
and then you probably have to increase the length of the particle study
