| Abstract: | Not every calorie in the PowerBar(R) consumed by the cyclist is converted into mechanical energy. A significant fraction is converted into thermal energy, which must be expelled in order to continue cycling. The primary cooling mechanism is the evaporation of water from the cyclist's skin and lungs. Using a damp towel to simulate the cyclist's naked skin covered with perspiration, we investigate the effects of air flow over the "skin" and covering the "skin" with various kinds of clothing. |
