Abstract

Abstract

A new method was provided to calculate the heat transfer coefficient of steam jet condensation in water by combining the average heat transfer coefficient and pressure oscillation main frequency through penetration length of stem plume, based on previous analysis model of steam jet condensation and oscillation main frequency correlation. Moreover, the pressure oscillation main frequencies were obtained experimentally at different steam mass fluxes and water temperatures, and the present and previous data were used to calculate the average heat transfer coefficients, and the values were within 1.71~2.93 MW/m~²·℃. The results indicated that the heat transfer coefficients were almost constant at various steam mass fluxes, and increased firstly and then decreased with the water temperatures.
