DETAILED THEORETICAL AND EXPERIMENTAL STUDY ON A LARGE MHD GENERATOR,
Abstract
Results of experiments carried out in a large MHD generator have been previously reported. Further results are described which led to a good understanding of MHD phenomena over a wide range of operating conditions and the detailed agreement between theory and experiment is examined. The good agreement indicates the feasibility of predicting MHD generator performance in detail. By a systematic study of the numerous data obtained, the magnitude of the different losses was determined with precision and the generator performance calculated over the wide range of running conditions. The theory used to describe the performance is one-dimensional, the friction and heat transfer coefficients have been determined experimentally. The use of this theory allowed the detailed calculation and agreement with experiment for more than twenty runs using as the only parameters the varying inlet and loading condition. Determination of shock location, effect of the boundary layer separation and electrode losses due to the Hall field are introduced in these calculations and the influence of these different effects is shown in detail.
