The present paper describes the results of a series of microgravity experiments on the so-called self-wetting fluid that is characterized as a fluid showing an increase in the surface tension with increasing temperature. 1.5wt% of 1-butanol aqueous solution was employed as a self-wetting fluid in the present experiments, and reference microgravity experiments were also conducted for CFC-113 and ethanol/water solution as a comparison. Attention was focussed on the flow at the bubble/heater contact area, which was expected to be under a strong influence of the Marangoni effect. The experimental results showed an occurrence of a strong inflow at the nucleation site. Difference in the fluid flow-behavior at the bubble/heater contact area is discussed.
