Experimental and theoretical analysis of stresses, noise and flow in centrifugal fan impeller
D.V. Bhope,Pramod M. Padole +1 more
TL;DR: In this article, experimental and finite element approaches have been discussed to study the stresses in centrifugal fan impeller, and the effect of the stiffening rings on the stresses, noise and fluid flow has been also investigated and discussed.

Design of a Mixed Flow Pump Impeller Blade and its Validation Using Stress Analysis
TL;DR: In this paper, a design and stress analysis has been carried out on mixed flow pump impeller blades having different positions in the meridional annulus and the maximum Von Misses stress distribution was compared among the different blade positions.

Material Selection for Blades of Mixed Flow Pump Impeller Using ANSYS
TL;DR: In this article, the 3D model of a mixed flow pump impeller blade was developed using CATIA and with four different materials (Copper alloy, Bronze, Stainless steel and Titanium alloy) analysis was done in ANSYS 11.0 with similar loading and support conditions.

An equation solver for eigenvalue problems of cyclic symmetric structures
P. Balasubramanian,V. Ramamurti +1 more
TL;DR: Michimura et al. as discussed by the authors used complex arithmetic to reduce the analysis region to a repeating substructure; characteristic matrices are considered to be cyclic in nature; most of the decomposition operations involved in the complex stiffness matrix are done only once, also in real mode.

Design of a Mixed Flow Pump Impeller and its Validation Using FEM Analysis
TL;DR: In this paper, the authors evaluated the natural frequency and deformation of a mixed flow pump impeller with two different blade positions in the meridional annulus and found that the inlet inclined blade position was more suitable than the trapezoidal one.

Finite element analysis of the in-plane behaviour of annular disks
V. Srinivasan,V. Ramamurti +1 more
TL;DR: In this paper, a semi-analytical, one-dimensional finite element model was developed using a Fourier series approach to account for the circumferential behaviour of annular disks, which can be readily coded into any general purpose finite element program.

Static analysis of circumferentially periodic structures with Potters' scheme
V. Ramamurti,P. Balasubramanian +1 more
TL;DR: In this article, the Potters' scheme of solving simultaneous equations is modified for the above analysis and applied to different kinds of problems and results are compared, where each sector is assumed to be loaded identically and only one sector has been taken for the analysis.
