Performance evaluation of nanofluids in loop heat pipes and oscillating heat pipes
International Journal of Thermofluids, 2022 Nanofluids have been presented as media to enhance the heat transfer capabilities of thermal control systems and devices of both single and two-phase heat transfer modes. Since the addition of solid nanoparticles in a base fluid can significantly increase the thermal and transport properties of a given working fluid, it impacts other properties that ...
