Critical to disciplines such as fluid dynamics, environmental modeling, and material science, transport phenomena often involve complex three-dimensional temporal processes. The detailed simulation of these phenomena demands high temporal resolution, which can be computationally expensive and data intensive. To address these challenges, we introduce advanced 3D volumetric temporal super-resolution models [1,2] that leverage deep autoencoders to predict high-resolution temporal data from lower-resolution inputs. These models enhance the understanding of dynamic processes within a three-dimensional space, including turbulent flow, heat transfer, and chemical reactions. The models, compared against traditional costly high-resolution simulations, show exceptional performance where rapid temporal changes are critical, such as in predicting the evolution of environmental pollutants, modeling fluid dynamics in industrial processes, and understanding heat distribution in large-scale systems. By offering a computationally efficient way to achieve precise temporal higher resolution 3D predictions, these models open new possibilities for research and practical applications in various scientific and engineering fields.
