In the present work, for both a COSMOS-HP (Counter-Stream-Mode Oscillating-Flow Heat Pipe) and a dream pipe, the optimum conditions yielding the highest effective thermal conductivity and/or the highest operating coefficient are analyzed for oscillating flows of a given amplitude S. The parameters used in the optimization are the thermophysical properties of the operating liquid, the channel size and the frequency of oscillating flow. Based on the analytical results of the optimum conditions, both the optimum liquid and the optimum oscillating flow conditions are discussed. The highest effective thermal conductivity of COSMOS-HP is compared with that of a dream pipe, and it is found that the former is much higher than the latter.
