DEFINITION OF BOUNDARY OF NUCLEUS OF FLOW AND COEFFICIENT OF PRESSURE RECOVERY IN SHORT ROUND CHANNELS

Simple formulas which allow the position of boundary of nucleus of flow to be found with a minimum of experimental points and to calculate coefficient of pressure recovery are presented. These formulas are brought out for axially symmetric channels, but not excluded is the possibility of extending t...

Description
Summary:Simple formulas which allow the position of boundary of nucleus of flow to be found with a minimum of experimental points and to calculate coefficient of pressure recovery are presented. These formulas are brought out for axially symmetric channels, but not excluded is the possibility of extending the method to other cases. Use of the given method is especially convenient in the case of use of pneumatometric combs or tubes, transferred automatically a given program.
