? Dr. Kazuo Matsuura won the best paper award at the 15th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics (ATE-HEFAT2021), organized online by Prof. JP Meyer, University of Pretoria, South Africa, from 25th till 28th July 2021. The topic of the awarded paper was the compressible thermo-fluid flows of a jet engine cascade.
? So far, the energy dissipation function, which represents irreversible increase in entropy, has been used to quantify decrease in blade row efficiency. However, the contributions of rotational and irrotational motions were not separable in the original formulation. Dr. Matsuura proposed a new formulation for evaluating the energy dissipation function based on the Helmholtz-Hodge decomposition, applied it to the unsteady flow fields of stator-rotor interaction reproduced by high-resolution Navier-Stokes simulations, and solved the above problem.
? The computations were conducted using the supercomputer systems of the Japan Aerospace Exploration Agency (JAXA-JSS3).
