Abstract:Specific coating is sprayed on the external surface of bare brass tube with the designed surface distribution form. The experimental investigation of the vertical falling film absorption outside the bare brass tube and different circumferential coated tubes at high temperature is conducted. The effects of solution spray density and inlet temperature on the heat and mass transfer are studied. The result shows that the heat transfer coefficients and mass transfer coefficients at high temperature are higher than that at low temperature on different tubes; The heat transfer coefficients on the coated distribution tube arc higher than that on the bare brass tube, but the mass transfer coefficients on the coated distribution tube are lower than that on the bare brass tube.
