COSMOS Heat Pipe, which is a kind of oscillatory-controlled heat transport tubes, has strongly curved capillaries inside. The driving power of fluids in tube with strong curve was examined experimentally to estimate the operation coefficient (defined by a ratio of heat transport rate and added driving power) of COSMOS Heat Pipe. The result shows that the power to drive oscillatory flow in strongly curved capillary can be about twice larger than that of straight one under some conditions. Heat transport experiment was also carried out, and it was shown that the estimated operation condition of COSMOS Heat Pipe is fairly high.
