However, they can be very computationally intensive to run. Machine learning methods have been shown to reconstruct high-resolution single-phase turbulent fluid flow simulations from low-resolution inputs. This offers a potential avenue towards alleviating computational cost in iterative engineering design applications. However, little work thus far has explored the application of machine learning image super-resolution methods to multiphase fluid flow (which is important for emerging fields such as marine hydrokinetic energy conversion). In this work, we apply a modified version of the super-resolution generative adversarial network (SRGAN) model to a multiphase turbulent fluid flow problem, specifically to reconstruct fluid phase fraction at a higher resolution. Two models were created in this work, one which incorporates a physics-informed term in the loss function and one which does not, and the results are discussed and compared. We found that both models significantly outperform non-machine learning upsampling methods and can preserve a substantial amount of detail, showing the versatility of the SRGAN model for upsampling multiphase fluid simulations. However, the difference in accuracy between the two models is minimal indicating that, in the context studied here, the additional complexity of a physics-informed approach may not be justified.<\/jats:p>","DOI":"10.1115\/1.4053671","type":"journal-article","created":{"date-parts":[[2022,1,28]],"date-time":"2022-01-28T02:54:30Z","timestamp":1643338470000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":37,"title":["Using Physics-Informed Generative Adversarial Networks to Perform Super-Resolution for Multiphase Fluid Simulations"],"prefix":"10.1115","volume":"22","author":[{"given":"Matthew","family":"Li","sequence":"first","affiliation":[{"name":"Microsoft Search, Assistant, and Intelligence, Microsoft Corporation , Redmond, WA 98052"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher","family":"McComb","sequence":"additional","affiliation":[{"name":"Carnegie Mellon University Department of Mechanical Engineering, , Pittsburgh, PA 15213"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"33","published-online":{"date-parts":[[2022,2,21]]},"reference":[{"key":"2023022101015573800_","first-page":"1","article-title":"The Future of CFD in Engineering Design","author":"Bakker","year":"2006"},{"key":"2023022101015573800_","first-page":"1","article-title":"Introduction to CFD Basics","author":"Bhaskaran","year":"2002"},{"issue":"8\u20139","key":"2023022101015573800_","doi-asserted-by":"publisher","first-page":"2203","DOI":"10.1016\/j.ces.2004.11.046","article-title":"Numerical Modelling of Gas\u2013Liquid Flow in Stirred Tanks","volume":"60","author":"Lane","year":"2005","journal-title":"Chem.
