Numerical Investigation on Compressible Flow Characteristics in Axial Compressors Using a Multi Block Finite Volume Scheme

An unsteady two-dimensional numerical investigation was performed on the viscous flow passing through a multi-blade cascade. A Cartesian finite-volume approach was employed and it was linked to Van-Leer's and Roe's flux splitting schemes to evaluate inviscid flux terms. To prevent the oscillatory behavior of numerical results and to increase the accuracy, Monotonic Upstream Scheme for Conservat...

Turbulent Flow Through Valves of Reciprocating Compressors

The present work considers the modeling of turbulent flow in reed type valves of reciprocating compressors and is based on a simplified geometry of the actual valve, that is, a radial diffuser with axial feeding. Despite its simplicity the geometry chosen for the analysis has important flow features present in practical geometries. Due to its claimed capability to predict flow including feature...

Analytical Modeling of Discharge Flow Dynamics in Scroll Compressors

The dynami~ cha~:-acteristics of scroll compresso~: operation have been demonstrated and analyzed in a number of papers over the past decade. This paper discusses the modeling methods used to describe the scroll ~ompressor discharge dynamics. Nume~:ous models are required to accurately represent this complex dynamic p~:-ocess. These include the differential mass continuity and polytropic compre...
