We are excited to announce the publication of our new paper «Genetically-inspired convective heat transfer enhancement in a turbulent boundary layer» in the Journal Applied Thermal Engineering.
Our work uses an artificial intelligence approach based on linear genetic algorithms control to enhance convective heat transfer in a turbulent boundary layer on a flat plate. Six slot jets in crossflow are used as an actuator to define an open-loop optimal periodic forcing using carrier frequency, duty cycle, and phase difference as control parameters. The control laws are optimized with respect to the unperturbed boundary layer and steady jet actuation. This experimental investigation highlights the potential of machine learning control and the feasibility of using advanced algorithms with sophisticated measurement techniques.
