mesh size: getting worse results with finer mesh

I am using a model which is dealing with the turbulence and waves, the problem when I made the validation for the programme with the experiment data, it showed a good result; however, when i reduced the mesh size to get more accurate solution, the results getting far from the experiment data and the relative error between the experiment data and the numerical result increased and reached to 50% (when i used small mesh size)
why that happened????
any explain for that case??
Thank you in advance for any answer,

Possible reasons (among others):
The skeleton ran out of shampoo in the shower.
