Toward Optimization Using Unsteady CFD Simulation Around Kayak Hull

One-Dimensional Mathematical Model for Kayak Propulsion

“…We see that these are high estimates and well above the various passive hydrodynamic drag coefficients obtained in the literature. On the other hand, the curves obtained from the model suggest that the assumptions made and the resolution are not far fetched, as it is not difficult to find similar curves in the literature-for example, in the work of Leroyer [17] by numerical calculation, in Begon's [18] where a kayak ergometer is modeled, or in Labbé [22] or Buckmann's [24] works applied to Olympic rowing.…”

“…A complete formulation of the problem would involve a coupled fluid dynamics model for the medium together with a dynamic model for the hull-paddler system. Some models exists for this system, using different approaches: that of Leroyer et al [17] by using computational fluid dynamics (CFD), or that of Harrison et al [13] by means of smoothed particle hydrodynamics (SPH). In essence, these implementations seek to computationally reproduce the real scenario as faithfully as possible, which makes use of large computational resources.…”

“…There are also studies on the forces applied to the paddle blade and the power, accelerations and velocities that it produce in the hulls [9,12,15,16]. Additionally there are kinematics kayak models: the one of six degree of freedom proposed by Leroyer [17] or the one introduced by Begon [18] to calibrate a kayak ergometer in the most precise way.…”
