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.ivoryjinelle.com/top-offer-Dragon-Ball-Super-Goku-Vegeta-Super-Ball-LG-Stylo-6-Clear-Case-p103191-quick-deal/
