Fernandes, G. D., Gandur, N. L., Santos, D., Maldonado, V. “…Results In this study, the drag of a realistic model of a male runner is calculated by computational fluid dynamics for a range of velocities. …”

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. …”

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. …”

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). …”

Beaumont, F., Legrand, F., Bogard, F., Murer, S., Vernede, V., Polidori, G. “…This study aims at modelling the aerodynamic interaction between a world-class runner and several pacers running in line, the objective being to determine the best drafting position in terms of potential speed gain and running time. Computational Fluid Dynamics calculations were performed to determine the aerodynamic drag forces exerted on the runners. …”

Banks, J., Phillips, A. B., Hudson, D. A., Turnock, S. R. “…The dynamic forces acting on a swimmer`s body are notoriously difficult to measure experimentally, thus motivating many researchers to use computational fluid dynamics to assess the propulsion and resistance forces. …”

Arias , F. J. “…Utilizing the raindrop collisional model and with the help of computational fluid dynamics (CFD), it is shown that the probability of collision with respiratory droplets is not always increasing with the approaching velocity of the runner but rather there is a maximum velocity threshold at which the efficiency of collision drops.…”

Beaumont, F., Bogard, F., Murer, S., Polidori, G., Madaci, F., Taiar, R. “…A simulation model based on Computational Fluid Dynamics (CFD) methods are used to analyze aerodynamic effects while physiological parameters are experimentally recorded using a lightweight ambulatory respiratory gas exchange system (Cosmed K5©). …”

“…In order to determine just how much influence "aerodynamic trickery" had in getting Kipchoge within 26 seconds of the mythical 2 hour barrier, we decided to run a series of computational fluid dynamics using STAR-CCM+, which is part of Siemens` Simcenter portfolio of simulation tools.…”
