Characterisation of Segregation by Dynamic Neutron Radiography
Languages of publication
Dynamic neutron radiography is an advanced non-destructive technique to visualise and analyse different types of segregation phenomena in technically important objects. Here we describe applications on calorimetric devices studied during operation. Segregation behaviour in the water separator and formation of clogging in the tube system of absorption-type refrigerator is studied. Separation of lubrication oil on the surface of the cooling agent in the evaporator puffer of compression-type cooling units, and inhomogeneous distribution of the working fluid in thermostats is discussed.
