Abstract
This paper describes the investigation on an epoxy model of a channel cover of bleed condenser, by three-dimensional photoelasticity. The channel cover is a thick plate with two nozzles which are connected on one side to pipes carrying water vapor/water under high pressure. A flat tube plate is connected on the other side by means of sixteen bolts around the periphery with high initial bolt forces.
The photoelastic model of the channel cover was made by machining a cast epoxy block (Araldite CT200). The stress distribution along critical sections of the model and the regions of maximum stresses and their values were determined. The prototype stresses were calculated from experimentally obtained values of model stresses, using simiilitude laws.
