Although the traditional automatic ball balancer (ABB) has numerous advantages, it has two major deficiencies, i.e., it has a limited balance stable region and it increases the vibration amplitude of the rotor at transient state. These deficiencies limit the applicability of ABBs. In this regard, a new type of ABB called “the Ball-spring autobalancer” has been proposed to resolve the mentioned ...

this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...

In this research, three dimensional transient simulations of explosion shockwaves have been performed by using computational fluid dynamics (CFD). For this purpose, the characteristics of explosive mass and the geometry of explosion environment have been imported to Ansys Fluent CFD software. The simulation results have been validated by using experimental data obtained from literature. The com...
