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.

Thermal Performance of a Plate Fin Heat Sink with Half Round Pins using CFD

As electronic devices continue to advance towards high performance and miniaturization measurements, heat dissipation problems have become a major obstacle to their growth. Moreover, the conventional method of air cooling did not fulfil the heat dissipation criterion of high density. Many scientists have researched the thermal efficiency of heat sinks, but the effects of half round pins on plate fin heat sinks have not yet been explored in the best possible way. In this work, a CFD model is developed to evaluate the effect of half round pin on the thermal performance of plate fin heat sinks, compared with literary experimental data. Here in this work, a constant heat flux of 18750W m2 along with a variable value of inlet air flow i.e. 0.00092, 0.00218, 0.0033 and 0.00433 kg s has been applied. In particular, the plate fin heat sink subject to impinging flow was compared to the conventional design Plate fin heat sink without half round pins . Variation of conventional thermal resistance is compared with the approach proposed in the air mass flow rate of different values. The results of this study show that the base temperature along with the thermal resistance of the heat sink with half round pin is lower for the proposed design. Nusselt number in proposed approach is found to be 28.98 higher than the conventional design at various values of the air mass flow rate due to increase in average heat transfer coefficient. Therefore, the developed approach has strong potential to be used to improve the thermal performance of heat sinks and hence to develop more advanced effective cooling technologies.

A Literature Review on the Role of Zycotherm as an Additive used in Bitumen

Water is one of the prominent damaging elements in asphalt pavement due to its enormous detrimental effects on pavement performance. Moisture damage induced by the actions of water reduces the strength as well as durability of asphalt mixtures, tends to cause various types of distress such as potholes, stripping, and others to the pavement, formed by lack of cohesion and adhesion. To sort out this problem, the modification of bitumen is needed to enhance its properties for pavement surface. Ergo, the current paper introduces the findings of prior research studies on Zycotherms effect as an anti stripping agent, recently developed, chemically reactive nanomaterial that imparts strength to the surface of the pavement. In this study, optimum bitumen content by Marshal Mix Design, without and with necessary dosages of Zycotherm upgraded from Zycosoil and alterations in properties are reported through various tests.

Numerical Investigation of Solar Air Heater Duct using Broken‘S’ Shaped Ribs Roughness on Absorber Plate

The solar air heater has an important place among solar heat collectors. It can be used as sub systems in many systems meant for the utilization of solar energy. Possible applications of solar air heaters are drying or curing of agricultural products, space heating for comfort regeneration of dehumidifying agents, seasoning of timber, curing of industrial products such as plastics. When air at high temperature is required the design of a heater becomes complicated and very costly. As far as the ultimate application for heating air to maintain a comfortable environment is concerned, the solar air heater is the most logical choice. In general solar heaters are quite suitable for low and moderate temperatures application as their design is simple. These solar air heaters have low heat transfer efficiency which can be improved using geometrical modifications like optimizing duct geometry or adding artificial roughness. The use of artificial roughness on the underside of the absorber plate is an effective and economic way to improve the thermal performance of a solar air heater. Several experimental investigations, involving different types of roughness elements, have been carried out to improve the heat transfer from the absorber plate to air flowing in solar air heaters. In this paper the CFD analysis on heat transfer and friction in rectangular ducts roughened with broken‘S’ shaped ribs has been presented. The relative gap width g e is varied from 0.5 to 2.5 and other parameter are constant. The effects of gap width g e on Nusselt number, friction factor and thermo hydraulic performance parameter have been discussed and results compared with smooth duct under similar conditions. It is found that the maximum heat transfer and friction characteristic at a relative gap width of 1.
