Bulk acoustic streaming imputing the equations

Hello everyone.

I am trying to reproduce an acoustic streaming simulation using COMSOL version 6.2. With the domain and boundary couplings, I am not able to achieve the results presented in the article: the values I obtain show a difference of up to 10⁻³ orders of magnitude. For this reason, I am trying to manually introduce the equations as the author did. I have used all parameters identical to those of the author. Could anyone with experience in acoustic streaming and manual equation implementation help me? Below are my results and the author’s results. I have run tests using both the thermoviscous acoustics and pressure acoustics modules.!
