In the present paper, the optimum conditions are investigated for development of the oscillation-controlled heat transport tube (the so-called dream pipe). First, it is shown that the effective thermal diffusivity reaches a maximum at the tube radius under fixed frequency and amplitude conditions. A correlation equation between the tube radius and frequency for the optimum condition is developed. The relationship between the tube radius and frequency for the optimum condition gives a transition frequency on the frequency characteristic curve of the effective thermal diffusivity for a fixed tube radius. Next, a concept of heat transport efficiency accounting for oscillation power is presented, and it is shown that the efficiency also reaches a maximum at the optimum condition for effective thermal diffusivity.
