  6. 5. Bubble Dynamics on Artificial Nucleation Sites in Boiling Heat Transfer

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Yuqing Zhang; [2021]
    Keywords : ;

    Abstract : Pool boiling heat transfer is a complicated scientific problem due to the complex phase change process. In recent years, with the development of nuclear technology, microelectronics and space exploration, more attention has been paid to boiling which present great potentials for the thermal management in these applications because nucleate boiling has much better heat transfer performance than single-phase fluid, while bubbles, including their departure frequency and diameter and the interaction between bubbles plays an important role in determination of the heat transfer performance.
