doc#118 | must, therefore, aim at a reduction of the | anode | loss. The following possibilities exist |
doc#118 | to reduce electron heat transfer to the | anode | for a given power output. 2. Continuous |
doc#118 | Continuous motion of the arc contact area at the | anode | by flow or magnetic forces. 3. Feed back |
doc#118 | Feed back of the energy transferred to the | anode | by applying gas transpiration through the |
doc#118 | by applying gas transpiration through the | anode | . The third method was, to our knowledge |
doc#118 | energy balance for a transpiration cooled | anode | as well as the effect of blowing on the |
doc#118 | voltage. Gas injection through a porous | anode | (transpiration cooling) not only feeds |
doc#118 | feeds back the energy transferred to the | anode | by the above mentioned processes, but also |
doc#118 | of dissociation or chemical reaction. The | anode | material was porous graphite. Sintered |
doc#118 | stand and of two different models of the | anode | holder. The cathode consisted of a <frac14> |
doc#118 | establish the required electrode spacing. The | anode | in figure 2 was mounted by means of the |
doc#118 | in figure 2 was mounted by means of the | anode | holder which was attached to a steel plug |
doc#118 | disk. The transpiring gas ejected from the | anode | formed a jet directed axially towards the |
doc#118 | against contamination of the arc by air. The | anode | consisted of a <frac12> inch diameter porous |

doc#118 | uniformity of the flow leaving the anode. The | anode | plug (Figure 2) was inserted into a carbon |
doc#118 | plug (Figure 2) was inserted into a carbon | anode | holder. A shielded thermocouple was used |
doc#118 | served for simultaneous measurement of the | anode | surface temperature and the temperature |
doc#118 | and the temperature distribution along the | anode | holder. Three thermocouples were placed |
doc#118 | locations in the aluminum disk surrounding the | anode | holder to determine its temperature. </p> |
