1Prediction of Dynamic and Aerodynamic Characteristics of the Centrifugal Fan with Forward Curved Blades显示文摘The main aim of this paper is determine the centrifugal fan with forward curved blades aerodynamic characteristics based on numerical modeling. Three variants of geometry were investigated. The first, basic 'A' variant contains 12 blades. The geometry of second 'B' variant contains 12 blades and 12 semi-blades with optimal length[1]. The third, control variant 'C' contains 24 blades without semi-blades. Numerical calculations were performed by CFD Ansys. Another aim of this paper is to compare results of the numerical simulation with results of approximate numerical procedure. Applied approximate numerical procedure [2] is designated to determine characteristics of the turbulent flow in the bladed space of a centrifugal-flow fan impeller. This numerical method is an extension of the hydro-dynamical cascade theory for incompressible and inviscid fluid flow. Paper also partially compares results from the numerical simulation and results from the experimental investigation. Acoustic phenomena observed during experiment, during numerical simulation manifested as deterioration of the calculation stability, residuals oscillation and thus also as a flow field oscillation. Pressure pulsations are evaluated by using frequency analysis for each variant and working condition.Jií Polansky László Kalmár Roman Gápár 2013Journal of Thermal Science2013,22,6:2
