Tanaka, T., Hashizume, S., Kurihara, T., Isaka, T. “…Vortex generation was obtained using computational fluid dynamics, and the fluid force of six vortices was determined from the vortex circulation, swimmers' segment velocity, and length. …”

Maddocks, P., Walker, A. D. “…This paper presents an aerodynamic investigation into the effect of arm position on drag using Computational Fluid Dynamics. The lowest drag was achieved by moving the hands/arms into a higher position in conjunction to narrowing the elbows better guided the air over the rider`s head and away from the centre of the rider`s body. …”

Tanaka, T., Hayashi, T., Isaka, T. “…This study aimed to reveal the propulsive and braking mechanisms of breaststroke kicks by simulating vortex generation using computational fluid dynamics (CFD). Kinematic data during the breaststroke kick and a three-dimensional digital model were collected to conduct CFD for a male breaststroke swimmer. …”

Taylor, M., Butcher, D., Crickmore, C., Walker, A. D. “…On a flat road, at race speeds, aerodynamic drag is the main resistive force a cyclist must overcome. Computational fluid dynamics (CFD) can be a useful tool to predict and understand the complex flow and, therefore, drive developments to reduce drag. …”

Coloretti, V., Russo, G., Fantozzi, S., Cortesi, M. “…To assess thrust force, indirect techniques (video-based analysis or computational fluid dynamic) are more time-consuming than direct ones (tethered swimming with load cell or pressure sensors system). …”

Bolon, B., Pretot, C., Clanet, C., Larrarte, F., Carmigniani, R. “…The interaction is quantified for a large range of relative positions and for three speeds corresponding to cruising, average, and sprint swimming. The associated computational fluid dynamics study using OpenFoam allows us to determine the relative positions that optimize the drafting during an open-water race: just behind a lead swimmer or at the level of the hip of a neighbor, with reductions of drag of 40% and 30%, respectively.…”

Fernandes, G. D., Maldonado, V. “…Methods We evaluated the performance of an elite marathon runner from an energetic standpoint, including drag values obtained through Computational Fluid Dynamics (CFD). In varying simulations for different pacing strategies, the energy for both the main runner and his pacer were conserved and the total race time was calculated. …”

Coloretti, V., Russo, G., Fantozzi, S., Cortesi, M. “…The latter methods extrapolate Ft directly, such as tethered-swimming or pressure sensors, while the former includes computational fluid dynamics, inverse dynamic estimation and Ft estimation from the swimmer`s active drag (Da)(Santos et al., 2021; Takagi et al., 2021). …”
