The relative drag coefficient of the back swimmer was lower (about 56% of the leading swimmer) for the smallest inter-swimmer distance (0.
Therefore, the aims of the present study were: (i) to describe the pressure profile around the swimmers in drafting through CFD analysis; (ii) to assess the drafting distances effect in the drag coefficient; (iii) to assess the distance in which the drag coefficient of the back swimmer is equal to the drag coefficient of the leading swimmer, considering various flow velocities.
This distance was measured from the toe tips of the leading swimmer to the head vertex of the back swimmer.
A HISTORIC Birmingham swimming pool is said to be on course for welcoming back swimmers after closing for 15 months.
