Four types of undulated cylinders with streamwise undulation. transverse undulation. in-phase undulation and antiphase undulation are employed to investigate the undulation-axis effect on the structure of heat transfer around wavy cylinders. The flows around these undulated cylinders are numerically simulated by large eddy simulation at Re = 3000. https://www.jmannino.com/super-super-University-of-Arizona-Primary-Mark-iPhone-14-Plus-MagSafe-Case-p76978-deal-zone/
