Data Visualization of Large-Scale Unsteady Fluid Simulation in Aeronautical Engineering

Abstract

  This article explains a data visualization of large-scale unsteady flow simulation using high-order unstructured methods in aeronautical engineering. First, a data structure of the flux reconstruction (FR) method is presented focusing on a difference from the conventional finite-volume method which has been used for steady flow simulations such as the Reynolds averaged numerical simulation. Then, we introduce a showcase for a large-scale direct numerical simulation around a low-pressure turbine blade. The simulation was performed by an open-source flow solver PyFR, and a visualization of unsteady vortex field is presented with a brief introduction of an in-situ visualization with PyFR. Finally, the outlook and possible issues are discussed for the in-situ visualization of unsteady flow simulation.
