摘要

流体动力学是众多工程应用的关键科学领域。该领域的实验工作需要精心的设置和昂贵的图像捕捉设备,尤其是在考虑复杂现象的细节时。在这项工作中,我们研究了超分辨率生成对抗网络(GANs)的应用,通过提升低分辨率实验图像的分辨率来获得高分辨率结果。

Enhancing experimental image quality in two-phase bubbly systems with super-resolution using generative adversarial networks

Enhancing experimental image quality in two-phase bubbly systems with super-resolution using generative adversarial networks

Fluid Dynamics is a key scientific field to multitudes of engineering applications. Experimental work in this field requires careful set-up and expensive image-capturing equipment, particularly when considering the finer details of complex phenomena. In this work, we study the application of super-resolution Generative Adversarial Networks (GANs) to achieve high-resolution results by upscaling lower-resolution experimental images.

We train GANs proposed for natural images on a bubbly flow experimental Fluid Dynamics dataset and compare common super-resolution evaluation metrics to domain expert assessments of the upscaled images. We find that these models achieve promising results, as evaluated by experts, and transfer learning from natural images translates to better performance overall. Attention mechanisms are found to be particularly useful in recreating sharper details. On the other hand, traditional super-resolution evaluation metrics are found to align poorly with expert perception of quality, signaling the need for better systematic evaluation methodologies in this domain.

期刊介绍: The International Journal of Multiphase Flow publishes analytical, numerical and experimental articles of lasting interest. The scope of the journal includes all aspects of mass, momentum and energy exchange phenomena among different phases such as occur in disperse flows, gas–liquid and liquid–liquid flows, flows in porous media, boiling, granular flows and others. The journal publishes full papers, brief communications and conference announcements.
