The paper considers results of computational modelling for dispersions flows in an upflow of isolating medium applicable to the process of hydraulic separation of mica ores. Methods of computational hydrodynamics reveal differences in distribution of volume density and average particles velocity according to the height and cross-section of the gravitational unit model depending on their form and dimensions. The obtained data may be employed for optimizing of hydrodynamic characteristics of certain elements in a hydraulic separator. Fig. - 2, Table - 1, Ref - 5. UDC 681.5 Morozov I.N., Bogatikov V.N. Indirect Damage Assessment Based on Condition of Processing Equipment // Scientific articles of KSC RAS. Information Technologies. - Apatity, 2010. - Iss. 1. - Р. 129 - 130. The paper considers technique of damage assessment depending on equipment condition. The concept of index is introduced as a criterion of quantitative damage estimation due to incomplete information. The article analyses an example of damage estimation caused by the functioning of catalytic gases purification unit at weak nitritic acid production. Indirect estimation is stated to be possible for damage of environment, equipment, control system and other objects when there is lack of exact information on cost parameters of the damage.
