| Abstract |
Design of exhaust hoods is an important factor in the collection of pollutants close to the source. A classification of mobile hoods used in welding is presented, and a method and a test set up especially designed for study of the influence of disturbing currents on the air velocity distribution in the range of action of the hood are described. Using isotachs the changes caused by disturbances are shown. The results confirmed the usefulness of the method, especially for studying small hoods. Further research to determine "exhaust spectra" of hoods is proposed to give designers a more solid basis for increasing the efficiency of ventilation systems. |
