Thus, the calculation does not require the addition of a further field section for the iron; the number of integration constants is not increased. The iron saturation needs to be taken into account because for the operation of a self-excited MHD generator it is necessary to have a curved voltage-current characteristic. Furthermore, greater channel heights require establishing certain ranges of saturation within the iron, in order to get the desired curved voltage-current line. With small channel heights the problem of saturation might exist in avoiding saturation in certain parts of the magnetic circuit. In both cases the equations mentioned in this report are applicable. Moreover, preparations were made to describe the electrical working conditions of the MHD generator. By limiting operation to small slips and by implying saturation it is possible to define impedances, which, in principle, shows that the working condition of an MHD generator has some analogy to that of the conventional induction generator. A corresponding equivalent circuit could also be developed. The power and the losses are calculated according to the instructions in [1].</p></div>","PeriodicalId":100032,"journal":{"name":"Advanced Energy Conversion","volume":"5 1","pages":"Pages 83-91"},"PeriodicalIF":0.0,"publicationDate":"1965-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0365-1789(65)90015-9","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74200833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One had a rhenium emitter and a nickel collector surrounded by a nickel guard ring. The other had a tungsten emitter and nickel collector and guard. Both had interelectrode spacings of 0·005 in. The collectors and guard rings could be kept at the same temperature and potential. Both converters were capable of delivering large currents. The WNi converter at <em>T</em><sub><em>E</em></sub> = 2235° K developed over 40 W/cm<sup>2</sup> at 0·6 V) at the electrodes. At each emitter temperature the ReNi converter had maximum output at a lower optimum cesium pressure than that for the WNi converter. At equal emitter temperatures and current densities the ReNi converter had higher output voltages. It is believed this is a result of the lower cesium pressure which enabled the collector work function to be lower. The ReNi converter at 2150°K had a usable output at 15 A/cm<sup>2</sup> of 16·8 W/cm<sup>2</sup> and a calculated efficiency of 19·8 per cent. An analysis based on the assumption that at each current density the current is limited by a maximum negative potential in the system, suggests that the variation of output voltage with current is primarily a result of a variation in the maximum potential point. This analysis also suggests that there is a double sheath at the emitter, i.e., negative sheath next to the emitter followed by a positive ion-rich sheath.</p></div>","PeriodicalId":100032,"journal":{"name":"Advanced Energy Conversion","volume":"4 4","pages":"Pages 195-196, IN1, 197-221"},"PeriodicalIF":0.0,"publicationDate":"1964-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0365-1789(64)90020-7","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84316151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
