Numerical study on the aerodynamic drag of drafting cyclist groups

This paper presents a Computational Fluid Dynamics (CFD) investigation of the aerodynamic effects of drafting in cycling. In drafting, cyclists ride close behind each other to reduce aerodynamic drag. The CFD simulations for single cyclists and for a group of two cyclists are successfully compared with wind-tunnel measurements. Both CFD simulations and wind tunnel measurements show that also th...

Drafting with Sequences

The numbers on the inner circle are those that exist in the modular arithmetic. If we continue beyond 7, as shown in the outer ring, the numbers wrap around the wheel. Numbers on the same spoke are equivalent. For example, 0 and 8 are equivalent, 1 and 9 are equivalent, 2 and 10 are equivalent, and so on. Another way to look at it is that when 9 is introduced into modular arithmetic with 8 shaf...

Drafting Indemnification Clauses

A typical indemnification clause requires the indemnitor to “indemnify and hold the indemnitee harmless.” It might also require the indemnitor to “defend” the indemnitee. While most legal authorities agree that the obligation to defend is different from the obligations to indemnify and hold harmless, many regard the promises to indemnify and hold harmless as synonymous, suggesting that either b...
