Summary
Experiments of ammonia-water falling film absorption were performed in magnetic fields of different intensities and different directions as well as under varied operating conditions. Experimental results showed that the outlet concentration of ammonia-water, the outlet temperature of cooling water and the amount of absorption heat and mass in downward magnetic field are higher than those in non-magnetic field. However, all of them decreased in the upward magnetic field. Therefore, it can be concluded that the magnetic field with the same direction as falling film enhances the absorption, and the magnetic field with the direction against falling film weakens the absorption of ammonia-water. The results also showed the effect of magnetic field on absorption was more obvious in solutions with low inlet concentration. The influences of the cooling water flow rate, the cooling water inlet temperature and the solution flow rate on absorption in magnetic field were similar to those without magnetic field.
