## Abstract Nucleate boiling heat transfer coefficients were measured on a horizontal heated wire during the pool boiling of nonβazeotropic mixtures of ammonia/water. The experiment was carried out at pressures of 0.4 and 0.7 MPa, at heat fluxes below 2.0 Γ 10^6^ W/m^2^, and over a range of mass fr

β¦ Synopsis
A correlation of nucleate pool boiling heat transfer coefficients in ammonia/water mixtures was proposed on the basis of measured heat transfer data on a horizontal heated wire. The correlation was derived using both the fraction difference between vapor and liquid, y 1x 1 , and the temperature difference between dew and bubble points, βT E . It can predict the heat transfer coefficients of the mixtures during pool boiling within an accuracy of Β±20% over the entire fraction range for heat fluxes below 1000 kW/m 2 , which corresponds to the experimental range performed by Inoue et al. [1]. It was clarified that the coefficients more strongly depend on y 1x 1 than on βT E for ammonia/water mixtures, while the heat transfer coefficients mainly depend on βT E for Freon (DuPont's trade name) mixtures.

## Abstract The aim of this work is to present a critical examination of both the available experimental data and the performance of the available mixture boiling heat transfer correlations for ammonia/water mixture. First, a selection and comparison of the experimental database found in the open l
The effect of mass concentration of magnetic particles and an applied magnetic field on pool boiling heat transfer of water-based magnetic fluid on a horizontal heater was investigated. The experimental results show that high-concentration magnetic fluid deteriorates boiling heat transfer, while mid
