Abstract: To decouple dimensional flow perturbation quantities, a probe optimization method is proposed for multi-wire constant temperature anemometry in transonic flow conditions. Historically, hotwire measurements of density, velocity, and total temperature fluctuations in transonic flows are challenging… read more here.

DOI: 10.2514/1.j062664
Abstract: This paper presents a neural-network-based turbulence modeling approach for transonic flows based on the ensemble Kalman method. The approach adopts a tensor-basis neural network for the Reynolds-stress representation, with modified inputs to consider fluid compressibility.… read more here.
