Design and Development of Composite Blower for Low Noise Using FEM

This work deals with the study of modelling and analysis of an underwater vehicle centrifugal blower. In the chapter one gives brief idea of blower functions and performance. The second chapter presents a brief report on literature survey, which reviews the present status of research in the field of theoretical analysis of stresses, and deflections on centrifugal blower. Chapter three covers the overview of Fiber reinforced plastic materials and properties of composite material used in this thesis. Chapter four explains the finite element method and describes element types used in this thesis. Chapter five gives modeling and meshing of blower. In chapter six, the testing of the blower and experimental results are presented and discussed. In chapter seven the static and dynamic behavior composite blower with different layups are presented. In chapter eight the acoustic analysis performed on the blower discussed and how the noise reduced is presented. In chapter 9 the conclusions from the analysis were presented.
