Design optimization of an heat exchanger using Gaussian process

•The design of helically ribbed heat exchangers is optimized using Gaussian Process.•The optimization relies on a set of wall-resolved Large Eddy Simulations.•The influence of the rib shape on pressure loss and heat transfer is investigated.•Rib induced swirling motion is found detrimental to the he...
