Experiments on the flow boiling of zeotropic mixtures water-ammonia inside a internally spirally grooved horizontal steel tube with a 12mm average inner diameter were performed. Experimental conditions are 40 to 80 kg/(m^2s) in mass velocity, 0.7 MPa in pressure, and nearly 5 to 20 kW/m^2 in heat flux. The measured heat transfer coefficient reaches its maximum as the quality approaches to about 0.6 and decreases abruptly as the quality increases. The heat transfer coefficient were also compared with those for pure ammonia.
