0136 Study of Flow Characteristics Downstream of Annular Inlet Guide Vanes

Abstract

In this study, the flow instabilities downstream of inlet guide vanes are investigated by conducting experiment and performing a numerical simulation. An attempt is made to clarify the influence of number of vanes on the flow patterns including cells formation and the exit flow angle. Furthermore, the propagating angular velocity ratio of the instability for various values of vane angle β_2 and number of vanes is presented as a function of exit flow angle α_3
