After the drag is calculated, the next step is to verify that the calculation makes sense. However, a fist is not a standard geometry and there are no experiments that I can directly compare against. One way to achieve it is to modify the fist and gradaully change it to a standard geometry. A total of 12 cases will be compared and they are shown in Fig. 1.
