Review on Vibration Problems in Turbomachinery
Abstract: Vibration suppression of turbomachinery is an important engineering problem. Vibration caused by mass imbalance is a common problem in rotating the turbomachinery systems. Imbalance occurs if the principal axis of inertia of the rotor is not coincident with its geometric axis. Higher speeds cause much greater centrifugal imbalance forces, and the current trend of rotating equipment toward higher power density clearly leads to higher operational speeds. In this paper, a …

Modified Design Improvement Study and Optimization of a intake Manifold to Obtain Unequal Distribution of Velocity for Optimal Diesel Engine Performance
Abstract: Geometrical design of intake manifold has been found very significant for the better performance of an I.C. Engine. It becomes less effective at the intake manifold's runner's outlets due to an uneven flow distribution of the intake air. With an increase in velocity at the distribution channels, the presented study seeks to make this uneven velocity distribution nearly equal without requiring any additional significant changes to the entrance manifold's construction. …
