Experimental studies of horizontal flow effects in the presence of cavitation on erosion – free dampers
Аннотация
Abstract Based on cavitation studies, the obtained graphical dependencies for determining the horizontal hydrodynamic effect of the cavitating flow on erosion-free dampers at various stages of cavitation. These data supplement the results obtained earlier. Based on studies, the effect of cavitation on the work of erosion-free dampers was revealed. So, on average, horizontal ripple loads in the zone of the developed stage of cavitation increase by 1.7…2 times. Such a significant increase in loads necessitates taking into account the influence of cavitation when designing the downstream fastening plates with erosion-free dampers. The values of the horizontal hydrodynamic loads on the erosion-free dampers given in the work make it possible to establish the shear loads on the slabs of the water cube under cavitation. The results of this work can be used in design practice to assess the stability of slabs of waterfall fasteners with cavitating erosion-free dampers.
