Abstract: In axial compressors, control of the secondary flow is crucial for enhancing aerodynamic performance. Among various control strategies, vortex generators (VGs) are an effective passive method combining simplicity, cost-effectiveness, and reliability. This study investigates the… read more here.

DOI: 10.1177/09576509241231023
Abstract: The probability-based uncertainty quantification (UQ) methods require a large amount of sampled data to construct the probability distribution of uncertain input parameters. However, it is a common situation that only limited and scarce sampled data… read more here.
