Thermal management has a big impact on how long electronic gadgets last and how well they work. With the ever-increasing number of closely packed electronic devices, heat transport concerns in such devices are becoming increasingly common. Pulsating heat pipes (PHPs) are newly developed devices in which two-phase heat transfer occurs. The most favorable advantage of PHPs over conventional heat pipes is that the PHP does not have wick structure through which condensate returns for heating purpose. Many researchers have analyzed and performed studies on pertinent design of PHPs, but due to thermodynamics and hydrodynamics combined effect, the working mechanism of PHP is exceptionally multifaceted. Further, the use of nano-fluids has attained significant attention over the last few decades because of higher heat transfer capabilities. Researchers have suggested hybrid nano-fluids for power applications where more heating is required; however, this mechanism has not been completely explored. The present review explores the current research trends in PHPs in terms of its main features and working parameters based on experimental and numerical analysis as well as multiphase modeling.
