Hi,

I have created a reservoir with two wells (injection and extraction) and I am observing how cold water injected at one well reaches the initial warmer temperature at the other well. I am trying to extract data that tells me how the width and length (or simply area) of the temperature plume differs over time. So basically a time vs Temperature plot for the width and length of my plume.

Anyone any suggestions to how I could tackle this problem?

Thanks!

Karel

Dear Karel,

In COMSOL you can compute a volume / surface integral, in which you can put your own expression.

For example if you want to find the volume of the plume, you could integrate over the whole domain the expression: "T>300". This will count the volume where the temperature is higher than 300 K.

To find the area of the plume, you could integrate this expression on a surface with a surface integral. You can then select one of the cross sections in your domain or create one yourself.

The attached file shows the implementation in 4.4.

Best regards,
Frank

Frank,

Thanks a lot!

I got it all worked out now.

Hi Karel, have you considered a 3 dimensional problem or a 2D. Can you share the mph file. I would like to know how you resolved this problem. Even I am working on the similar problem what you addressed.
