How to introduce air around a heat exchanger design?

Dan.Ch · November 23, 2020, 14:05

Hello,

For my Bachelor's Thesis, I am working on a simulation of a Heat exchanger.

The design is simple. A heated metal plate is cooled with 3 pipes in the middle. I've successfully designed and ran simulations for this design.

Now I want to add air.

Basically, the whole heat exchanger geometry would be inside a new box (mesh) that will be air.

I've tried everything I could think of for e.g. used boolean to preserve tool bodies (metal plate + pipes) and also with just a single tool body (metal plate).

I always get a surface contact error in setup.

I can't seem to find any tutorial online so If you know something, please point me in the right direction.

Thanks

olease how did you mesh your plate heat exchanger with the 3 pipes?

can U make photo of Ur model
If this is complicated model U need to simplify some regions
