ENERGY TECHNOLOGY OF ASSESSMENT OF DYNAMIC LOADS IN HYDRAULIC TURBINES

Аннотация:

Determining dynamic loads is an important step in assessing the strength, reliability and service life of water turbines. The variety and complexity of dynamic processes in the flow part of hydraulic units cause great difficulties in their formalization and numerical simulations, even for the steady state near the best efficiency point. Experimental methods for determining dynamic stresses in the critical elements of full-scale water turbines, especially the blade impeller system, are expensive, and the equipment must be shut down for long periods of time to carry out preparatory work.
