DEVELOPMENT OF EXPERIMENTAL METHODS TO STUDY HETEROGENIC FLOWS IN THE CONTEXT OF HYDRAULIC HOISTING DESIGN

English abstract

In view of rapid decrease of resources of raw-material base of continental for-mations, problems of ore field development in the World Ocean become absolutely essential. They are connected with the progress of topical research of resource-saving methods intended to extract solid minerals. Construction of mining marine complexes on the basis of hydraulic systems for the extracted primary material hoisting is notable for high probability of their engi-neering implementation. Pump hydraulic hoisting and air-lift one are considered as the potentially productive alternatives to transport polymetallic concretions despite their high power intensity. The abovementioned sets the relevant research and de-velopment problem to improve accuracy of experimental methods. Subjects of the study are vertical high-speed unidirectional annular flows and disperse flows within blading sections of deep-water hydraulic hoisting. Objective of the research is to analyze the solid material transportability with the help of vertical three-phase flow in terms of annular and disperse flow structures as applied to hydraulic hoisting modeling. The objective is in the natural line with statement of the research and development problem. The idea is to decrease power intensity of hydraulic hoisting and to improve its efficiency owing to selection of reasonable consumable parameters while advancing both experimental calculation techniques and theoretical ones as well as implement-ing innovative designs. Originality is that for the first time the experimental methods have been devel-oped to analyze three-phase flow with an active role of solid particles using the im-proved experimental and technical basis. Innovative scientific finding is in the opening of previously unknown phenome-non titled conventionally «change of a leader» which is a definite stage in the de-velopment of dynamics of turbulent heterogeneous flows.
