Parameters affecting burnout heat flux in the nucleate boiling region
- Heat of evaporation: The heat of evaporation is the amount of heat required to change a liquid into a vapor. A higher heat of evaporation can lead to higher burnout heat flux in the nucleate boiling region.
- Temperature difference: The temperature difference between the surface and the boiling liquid affects the burnout heat flux. A greater temperature difference can result in higher burnout heat flux.
- Density of vapor: The density of vapor plays a role in determining the burnout heat flux. A lower density of vapor can enhance the heat transfer process and increase the burnout heat flux.
- Density of liquid: The density of the liquid also influences the burnout heat flux. A higher density of liquid can affect the heat transfer characteristics and the overall burnout heat flux.
- Surface tension at the vapor-liquid interface: The surface tension at the vapor-liquid interface affects the stability of the boiling process. A lower surface tension can lead to better bubble release and heat transfer, resulting in higher burnout heat flux.
Therefore, the correct parameters that affect burnout heat flux in the nucleate boiling region are heat of evaporation, density of vapor, density of liquid, and surface tension at the vapor-liquid interface.
