Figure 10: 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°.
