Theoretical Analysis of Volume/Weight Fraction of a Dual-Constituent Composite
Abstract: Conventional equations used in analysis of composite materials are modelled based on volume-averaging principle. The volume-averaging equations were re-evaluated to provide an alternative weight-averaging consideration as a result of the difficulty in practical determination of volume fraction of individual constituents of composite material, especially particulate composite. The equivalent weight-averaging equation analysis showed that density plays a significant determining factor in material selection of individual constituent; and composite density evaluated using …

Design and Simulation of IRFOC for SPWM Inverter-fed Induction Motor Considering Core Loss and Stray Load Loss
Abstract: The principle of field oriented control (FOC) or vector control (VC) of induction motors (IMs) is based on the control of both the magnitude and the phase of each phase current and voltage to achieve the decoupling control strategies between flux and torque. To control the flux and the torque precisely based on the FOC, core losses (CL) and stray load losses (SLL), which are generally neglected, should be considered …

A Model Approach of Controlling Coning in Oil Rim Reservoirs
Abstract: Water and gas coning in oil rim reservoirs poses serious hindrance to optimizing oil production in the thin oil beds as unwanted fluids tend to replace oil in the production stream. This invariably limits the ultimate oil recovery. In this study, semi-analytical models of estimating critical rate and optimum horizontal well placement were developed to control coning tendencies in oil rim reservoirs. The models were developed through semi-analytical analysis of …

Computation of Different Stresses Acting on Cantilever Beam Using Hyperbolic Shear Deformation Theory
Abstract: The shear deformation effects are more significant in the thick beams. The classical beam theory (ETB) is based on Bernoulli-Euler hypothesis and the classical plate theory (CPT) is based on Kirchhoff’s hypothesis. The shear deformation effects are more pronounced in the thick beams when subjected to transverse loads than in the thin beams under same loading condition. These effects are neglected in elementary theory of beam (ETB). In order to …
