FLUENT has well-validated physical modelling capable of delivering fast, accurate results for multiphysics applications, and has been widely applied in numerical simulation and is considered to be a very powerful CFD tool. As shown in Table 2, most of the published CFD works in the past ten years have applied FLUENT software, for example, References [4,16,48,[77][78][79][80][82][83][84][85][86][87][89][90][91][92][93]95,96,100,103,[105][106][107]. ...
... The wake region and recirculation zone were found to move under the wavy winglets compared with the conventional winglet, thus both wavy-up and wavy-down RWPs significantly enhanced the heat transfer performance. The wavy-up RWPs showed the best heat transfer performance but also had a relatively higher pressure-drop penalty and friction factor than Gholami et al. [100] numerically investigated heat transfer enhancement and pressure-drop penalty for fin-tube heat exchangers with 30 • attack angle for wavy-up
