Abstract Oil palm fibers have been developed as reinforcement in the composite. These can be produced from fruit, trunk, and frond of oil palm. In this review, fruit fiber for reinforcing composite was focused. consist empty bunch (EFB) mesocarp (MF) fibers. The chemical composition characteristics are described. Furthermore, mechanical properties reported to related surface treatment EFB MF Ap...

Currently, surface treatments lead to inducing a superficial layer of several nanometers up micrometer, which in some cases can be protective. In this experimental work, an oxide was generated under different atmospheres (CO2 and steam atmospheres) during the thermal aging treatment two maraging grades, 300 350. Afterwards, microstructural mechanically characterized by advanced characterization...

Stress Concentration Factors are significant in machine design as it gives rise to localized stress when any change in the design of surface or abrupt change in the cross section occurs. Almost all machine components and structural members contain some form of geometrical or microstructural discontinuities. These discontinuities are very dangerous and lead to failure. So, it is very much essent...

In the Modern scenario, the naturally available resources for power generation are being depleted at an alarming rate; firstly due to wastage of power at consumer end, secondly due to inefficiency of various power system components. A Combined Cycle Gas Turbine (CCGT) integrates two cycles- Brayton cycle (Gas Turbine) and Rankine cycle (Steam Turbine) with the objective of increasing overall pl...

In the field of mechanical engineering, steam turbine fault diagnosis is a difficult task for mechanical engineers who are confronted with challenges in dealing with copious amounts of uncertain information. Different mechanical engineers may have their own opinions about the system fault knowledge base that differs slightly from other mechanical engineers. Thus, to solve the problems presented...

Steam injection for power and efficiency augmentation in aeroderivative gas turbines has been commercially established for natural gas-fired cogeneration since 1980. Steam-injected gas turbines fired with coal and biomass are being developed. A performance and economic assessment of biomass integratedgasifier steam-injected gas turbine (BIGISTIG) cogeneration systems is carried out here. A deta...

The main purpose of this work is to conduct coupled CFD analysis of the steam flow in the secondary part of turbine and study thermal rotor/stator steady state. We consider a 11 stage high-pressure cylinder of a power steam turbine with extended terminal labyrinths. Domain of interest is only the secondary flow path of the cylinder, therefore the shroud and blades are beyond the scope of this w...

The boiler drum level control unit is one of the main parameter in the thermal power station. Currently the boiler drum parameters are monitored only by using MATLAB software. There is no automatic control available. In the proposed system the boiler drum parameters such as temperature level, pressure level, water level and Droplet identifier are measured and controlled by using embedded proces...

The antibiotic 2,4-diacetylphloroglucinol (DAPG), produced by some strains of Pseudomonas spp., is involved in suppression of several fungal root pathogens as well as plant-parasitic nematodes. The primary objective of this study was to determine whether Wood1R, a D-genotype strain of DAPG-producing P. fluorescens, suppresses numbers of both sedentary and migratory plant-parasitic nematodes. An...
