Grahic Jump Location
Thermographic phosphor and coolant temperature profiles were measured along the running length of the falling film
Grahic Jump Location
The mass fraction of the falling film for the present study is compared to the independent data of Burdukov et al. 19 and of Grossman and Alefeld 18
Grahic Jump Location
The absorber load is affected by the mass fraction, the pressure, the coolant temperature and the falling film mass flow rate
Grahic Jump Location
The mass absorbed is affected by the mass fraction, the pressure, the coolant temperature and the falling film mass flow rate
Grahic Jump Location
Overall Nu and Sh numbers were reduced from tests conducted at different pressures, mass fractions, coolant temperatures and falling film mass flow rates
Grahic Jump Location
Nu and Sh numbers were correlated from 0.62 and 0.64 mass fraction LiBr data and account for the effects of absorber pressure and coolant temperature
Grahic Jump Location
A point-by-point review of the error observed in the heat and mass transfer correlations
Grahic Jump Location
Decreasing the viscosity and surface tension improves the agreement between 0.60 mass fraction data and the correlations for the Nu amd the Sh numbers
Grahic Jump Location
The correlation for Nu and Sh numbers are compared to independent data which were reduced using Eq. (4) for the Nu number and Eq. 7 for the Sh number
