Stresses in centrifugal compressor test impellers

This report gives the details of a simplified design13; calculation method of stress analysis of Centrifugal13; Impellers. This method can be used for the quck estimate13; of stress levels in centrifugal impellers and can be used13; as a sort of i ni ti al gu ide to sel ect the mater i al a nd type of construction of impellers the design of which can be further refined by using other methods. This method13; also provides qu ick estimate of the growth of rCldial13; impellers at different locations to enable the selection of appropriate seal clearance
