|Abstract:||<p> Two phase flow induced vibrations is a field that has many inherent modelling difficulties, making research in the area challenging. In order to study the problem more closely, a two phase flow loop using Freon 11 had been designed and commissioned at McMaster University. The initial design required some modifications to make the loop as "user friendly" as possible. The final result meets this desired capability. </p> <p> The loop was designed so that research into vibrations in tube bundles could be carried out. A test section had been designed to facilitate this task. However, this design also required modifications. Additionally, new vibration monitoring instrumentation making use of light was developed to avoid the detrimental effects of Freon 11. The introduction of these items has resulted in a complete facility for the purpose of studying two phase flow induced vibrations. Preliminary experiments revealed a problem relating to tube tuning. Generally, the results are promising and some interesting new phenomena were observed as well. </p>|
