wheel circumference
3.For the solar energy solid adsorption rotary refrigeration system using activated carbon fiber-ethanol as its pair,one-dimensional uniform pressure field mathematical model along the circumference of adsorbent bed was adopted to carry out a static simulation calculation of the temperature field of the adsorption wheel bed.
4.Any of various machines in which the kinetic energy of a moving fluid is converted to mechanical power by the impulse or reaction of the fluid with a series of buckets, paddles, or blades arrayed about the circumference of a wheel or cylinder.
