The governing equations of piezo-thermoelastic materials show full coupling between mechanical, electric, and temperature fields. It is often assumed in the literature that in high-frequency oscillations, the coupling ...

This study presents a numerical simulation of stall control by using the casing treatment method which represents the passive control technique and also by using the air injection method which represents the active control ...

This study presents a numerical simulation of precursors and characteristics of rotating stall in a centrifugal compressor with vaned diffuser. The aim is to further understand the causes of stall inception, characteristics ...
