“…After this procedure, the process was carried out on Ansys Meshing Module. The surface area of the current computational domain has considered the CFD's criteria of the practice guidelines [8], [33] (figure 3). The domain was meshed with more than 42 million elements to represent the fluid as mentioned in previous reports [21].…”

Purpose The drag in walking, running, and sprinting locomotion can be assessed by analytical procedures and experimental techniques. However, assessing the drag variations by these three main locomotion’s (i.e., walking, running, and sprinting) were not found using computational fluid dynamics. (CFD). Thus, the aim of this study was two-fold: (1) to assess the aerodynamics of human walking, running, and sprinting by CFD technique; 2) compare such aerodynamic characteristics between walking and running. Methods Three 3D models were produced depicting the walking, running, and sprinting locomotion techniques, converted to computer aided design models and meshed. The drag varied with locomotion type. Results Walking had the lowest drag, followed-up by running and then sprinting. At the same velocities, the drag was larger in walking than in running and increased with velocity. Conclusions In conclusion, drag varied with locomotion type. Walking had the lowest drag, followed-up by running and then sprinting. At the same velocities, the drag was larger in walking than in running and increased with velocity.

Polo is a popular sport in New Zealand, Australia, the United Kingdom, and many other European countries. Polo is a vigorous sport involving players and horses moving at speed and can result in head injuries caused by falls. Helmets play a vital role in the safety and protection of polo players. This study investigates different hemispheric bumper shapes of the helmet to improve the impact resistance performance using finite element analysis (FEA) and Explicit Dynamic Analysis (EDA). The aerodynamic performance of the proposed helmet is investigated using computational fluid dynamics (CFD) to account for drag impact on the polo player's speed. These are investigated for impact resistance and the drag coefficient under different speeds. The EDA results show that the new proposed bumper will absorb the impact and reduce the energy transferred to the inside foam at a relative impact speed of 6.2 m/s, as recommended by the U.S. Consumer Product Safety Commission (CPSC), with a maximum total deformation of 4.42 mm compared to 4.19 mm and 3.85 mm for impact speeds of 5.9 m/s by the European standard PAS 015:2011 helmets for equestrian use and 5.42 m/s BS EN 1078 helmets for bicyclists' use, respectively. Additionally, under speeds ranging from 15 km/h to 65 km/h, the new helmet demonstrated a drag coefficient of 0.454, similar to that of the national team helmet, at 0.423.
