In this paper, we investigate the boiling phenomena in superfluid helium of 4He(HeII). It has been found that the four film boiling modes exist in HeII. They are named as silent, noisy, weakly subcooled and strongly subcooled film boilings. These modes occur depending on pressure, temperature, heat flux and experimental setup. We observed that the noisy film boiling occurred in the rectangular duct and the periodic oscillation of temperature and sound were generated. We present here the noisy film boiling model by measuring temperature and sound pressure. From the temperature spectrum, we specify that there is peak frequency fd. Defining the effective heat flux qα as the difference between the provided heat flux and critical heat flux, we discuss the relationship between fd and qα.
