Hi all,

i'm still confuse on aspect ratio defination. In few publised papers define the aspect ratio as (Height/width) but in other paper used hydraulic (diameter/channel lenght). So which one is the correct one?

thank you for you time.

Hi,

You can define it to be whatever is relevant to your situation. As you have noticed, when a paper talks about aspect ratio you have to be careful to understand exactly how they have defined it as it varies between authors.

I used to use Height/width or (H/L).

Take a look yourself:
