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 …

Identification of significant parameters for the production of Jatropha biodiesel using preliminary experimentation
Abstract: The current research work is on Jatropha biodiesel for finding the significant parameters in optimum biodiesel yield. The one factor at a time approach is applied in the esterification. The trans-esterification reaction is used by mixing of Jatropha oil and ethanol in the presence of catalyst KOH. After some time two products are formed a Jatropha biodiesel and a glycerin. The density of glycerin is more as compared to biodiesel. …
