Factors Leading to Major Casting Defects and their Influence on Productivity of Foundry

In recent times, with the constant utilization of natural resources, every manufacturing unit is turning towards a lean approach. Foundries are no exception to this. Although the fundamental responsibility of a foundry is simply to convert raw metal into a useful casting, it is imperative on their part that the output confirms with the quality as desired and is free from defects of any kind. However, there may be factors like the rate of cooling of molten metal being poured, mould properties, metallurgy of the molten metal being poured and the mould geometry and rigidity to name a few which may have their influence on the casting quality and the overall productivity of the foundry. While striking a balance between the quality and productivity, there may be certain deviations undertaken from the regular course that may lead to casting defects. This paper intends to highlight such interdependencies and suggest indirectly the most feasible means to control casting defects in order to ensure attainment of both quality and productivity. Casting defects considered for this work shall be those observed at a major scale and those which require adequate attention on account of frequency of occurrence. A conclusion shall be drawn towards the end dictating the major findings of the study.

Analysis and Design of Pre Cast Box for Road under Bridge and Road Over Bridge by using Staad Pro

A level crossing or a grade crossing is a place where railroad line and a street meet each other at a similar level. In the Urban regions for the most part the level intersections are checked by qualified railroad staffs that screen the train development and close the level intersection door to stop the meddling street traffic yet such shutting of entryways prompts gridlock in streets, makes loss of time the street clients and now and again likewise prompts a mishap. The best choices to kill the level going across are Road under Bridge RUB and Road over Bridge ROB . There are 3 fundamental strategies for development of street under scaffold. Box pushing strategy, Cut and spread strategy, moving method utilizing RH brace. In this paper a plan of Road under Bridge or Subway by Box Pushing Method is introduced. During that time, traffic is continuing overhead typically, ignorant of the development beneath. The no problematic nature of the cycle along with its inalienable wellbeing, effortlessness and economy make box pushing a valuable apparatus for the rehearsing structural designer. This paper means to carry a more noteworthy experience with the crate pushing cycle to the peruser and afterward give a few contemplations and rules to help engineers in planning an undertaking that can be assembled utilizing the container pushing strategy. Box pushing is a settled methods for designing ducts or passages under rail banks or streams to oblige street or rail traffic.

Hydrodynamics and Heat Transfer through Corrugated Channels A Review

The continually rising energy consumption pushes researchers and engineers to create more effective energy systems to better use energy sources. In order to manufacture more compact heat exchangers, which are used in air conditioning systems, chemical reactors, heat power plants and others, it is important to improve the heat transfer rate with an appropriate pressure drop. Currently many engineering strategies are applied to increase energy systems thermal transfer efficiency, such as surface changes, swirl flow creators, flow conditioners, additives etc. Researchers are also involved in applying these methods to further increase the reliability of energy systems, while many experimental and numerical details are available in the existing literature. Since the corrugated channel is a passive technique to maximise heat transfer, researchers have insisted that one or more passive active methods be used in corrugated channels to allow further changes. The purpose of this paper is to collect accessible research data based on the flow characteristics and the heat transfer rates across corrugated channels in particular. The previously obtained conception conditions, functional limits, and assumptions of energy systems are also discussed.

CFD Analysis for Heat Transfer Enhancement of a Corrugated Plate Heat Exchanger using Different Corrugated Channel Configurations

The flow properties of heat transfer across such corrugated channels are very distinct from parallel plate channels. The primary flow direction is parallel to the waviness of the channel of the corrugated channel, although the local flow direction is still changed due to the waviness of the channel. By flow recirculation, separation and re attachment, the thermal boundary layer formed on its walls is regularly disrupted and the convective heat transfer coefficient is thus increased. In this work, in corrugated channels, the convective heat transfer and pressure drop characteristics of flow have been tested numerically. On channels of uniform heat flux and fixed corrugation over a Reynolds number spectrum, 10000 = Re = 30000, numerical research was conducted. The impacts of channel configuration, variation in Reynold’s number, and concentration variations of nanoparticles in base fluid on heat transfer are discussed. As opposed to the traditional corrugated channel, a major heat transfer gain was associated with the proposed corrugated channel. Based on the nanofluid concentration, Reynold number and channel configuration of the corrugated channel, the average Nusselt number increased by a factor of 2.2 up to 2.8 compared to that of the semi circular corrugated channel. Compared with the effect of channel configuration variation, triangular corrugated channel was the best Nusselt numbers, followed by the shape Semi circular Triangular , and Semi circular corrugated channel with the lowest results.

Study of Improve Power Quality Issue through Different Load Combinations Parameters

The term electric force quality extensively alludes to keeping up an almost sinusoidal force circulation transport voltage at evaluated greatness and recurrence. Whats more, the energy provided to a purchaser must be continuous from dependability perspective. Despite the fact that power quality is basically a dissemination framework issue, power transmission framework may likewise have sway on nature of intensity. Reasons for power quality crumbling are clarified in next segment. With the ever increasing utilization of modern controls and hardware in mechanical, business, institutional, and legislative offices, the progression, dependability, and nature of electrical assistance has gotten very pivotal to many force clients. Electrical frameworks are dependent upon a wide assortment of intensity quality issues which can intrude on creation measures, influence delicate gear, and cause vacation, scrap, and limit misfortunes. Transient voltage changes can grievously affect creation broadened blackouts have a more prominent effect. Many force quality issues are effortlessly recognized once a decent portrayal of the issues is gotten. Shockingly, the pressures brought about by power issues regularly bring about unclear or excessively emotional portrayals of the issue. At the point when power issues occur, one must attempt to take note of the specific season of the event, its impact on electrical hardware, and any as of late introduced gear that might have acquainted issues with the framework.
