•Surfactant addition enhances water flow boiling heat transfer and increases CHF.•More nucleation sites and smaller bubble sizes exist in surfactant solution flow boiling.•Bubbles merging makes the middle nucleation sites neighbored by others lose its effectiveness.•Prevention of bubbles merging is...
