Stanowisko do badań kawitacji w przepływie wokół płata

Koronowicz J. , Wilczyński L.

tom nr 10

5-11

Artykul zawiera opis technologii wykonania stanowiska do badania kawitacji w przepływie wokól NACA 16-018; stosunkowo duże rozmiary płata pozwalaly obserwować kawitację w skali zbliżonej do rzeczywistej skali przebiegu zjawiska w maszynach przepływowych.

This article describes the process of building a station for examining the cavitation in the flow around the panel NACA-16-018. The relativery large size of the panel permitted to observe the cavitation in a scale approximating to the real scale of the phenomenon in fluid-flow machines. Considerable hydrodynamic forces acting on the panel and a required precision of reproducting the panel geometry called for non-typical processes of making it.

The paper dwells with the problems of modelling the flow around a wing tip and tip vortex cavitation. The theoretical bases of the vorticity method and vorticity calculation models for design and estimation of hydrodynamic characteristics of the hydrofoil are presented. Basic assumptions of a double layer lifting surface model are described. A double layer lifting surface model enables proper modelling of the phenomena occurring in the flow around a hydrofoil tip and especially the generation of a free vortices system.

There is a lot of Learning Management Systems which solve some distant learning problems or which are good addition to stationary lessons. They support wide scope of standards like SCORM [1] or IMS. They are commonly used to publish learning content and to perform tests. They have different types of remedies for „no direct contact" problem, like forums, video/chats etc. but often it's not enough for some types of classes.

The paper presents the problem of tip vortex cavitation inception in the flow around a screw propeller. The most recent experimental and theoretical results concerning mechanisms of tip vortex generation and vortex cavitation inception are reported.
