Pool boiling of both water and aqueous solutions of cationic surfactant Habon G in an open tank has been investigated by infrared thermography in combination with video recording- This technique provided information on the bubble dynamics, on the variations in wall superheat over an extensive region, and on irregularities in the behavior of nucleation sites. Heat transfer coefficient was enhanced considerably by the addition of Habon G in the range of concentration of 65–1060 ppm. This effect is more pronounced when the surfactant concentration is higher but there is diminishing as surfactant concentration is increased, with an optimum concentration, probably near 530 ppm Habon G.
