Abstract: Solenoid is an electromagnetically operated actuator. A typical application of solenoid is to operate valves in aircraft engine under harsh environmental conditions and high endurance requirements. Under these circumstances usage of higher hardness materials for spindle becomes unavoidable. Unfortunately these materials exhibit magnetic susceptibility. This cause higher flux leakage and reduces the efficacy of the solenoid. Solenoid having very high force to weight ratio over a range of stroke with limited envelope is much appreciated for aerospace and space applications. A novel method of introducing flux router (a nonmagnetic component) at an appropriate location in the solenoid geometry in order to divert the unused magneto motive force (MMF) into working air gap is discussed in this paper. Numerical simulations based on finite element methods is used for performance comparison of conventional and proposed solenoid keeping same applied MMF and simulation parameters for various flux

Abstract: This paper gives a brief introduction of research in the field of parallel and grid computing using java parallel processing framework (JPPF). It is observed that applied physics computations like Moment of Inertia, velocity, viscosity of liquid, elasticity etc. requires lot of calculations and also it should be precise to high degree of accuracy. This application calculates the Moment of Inertia of 11 types of bodies symmetrical in nature along with given axis of rotation. These 11 tasks are running parallel in JPPF grid in clusters environment of parallel computing. This application promotes the solution of such engineering problems with great accuracy and speed as platform independent parallel applications. The experimental results are obtained with the help of JPPF GUI monitoring and administration tool.
