Comparison of drag coefficient versus angle of attack acting on swimmer’s hand: (a) current CFD results (with appropriate sweepback angle and flow velocity in each phase), Bixler and Riewald [

5] CFD (velocity 2 m·s

^{−1}, sweepback angle 0°), Berger et al. [

6] experimental results (velocity 1 m·s

^{−1}, sweepback angle 0°) and Schleihauf [

15] experimental results (velocity 2 m·s

^{−1}, sweepback angle 0°); (b) current CFD study (with appropriate sweepback angle and flow velocity in each phase), Sato and Hino [

12] CFD, and Takagi [

16] (cited in [

12]) experimental results where flow velocity is 1 m·s

^{−1} and sweepback angle is 0°.
