Design and Performance Evaluation of Low-Speed Vertical Axis Wind Turbines with Wind Boosters using CFD Analysis

The use of wind based energy is quickly expanding over the planet. The goal of this study is to use computational methods of fluid dynamics to develop a novel model of VAWT including Windbooster for various rotor blades like two, three, and four blades in order to enhance effectiveness. CAD modelling approaches of vertical axis wind turbines including and excluding booster are created. Including all vertical axis wind turbine blade designs including and excluding booster, torque, power, and Coefficient of performance are compared.The performance of three blades on the basis of mechanical properties includingi wind amplifier is 29.9% greater than two blades using wind amplifier, and four blades using wind amplifier is 21.5 percent greater than three blades using wind amplifier, according to the findings. Because the mechanical energy created by a four-blade wind booster wasn't as great as it is including three blades, VAWT employing three-blade wind booster seems to be more effective than VAWT with a two- or four-blade wind booster. For improved mechanical durability, VAWT with three-blade wind amplifier is recommended.

A Comprehensive Analysis of DSTATCOM-Based Power Improvement

Power quality became one of the most critical challenges in today’s modern power system. Utmost primary factors of power quality issues are non-linear fluctuating loads, system interruption, load variances, infrequent loads, and arc furnaces. As a matter of fact, there is occurrence of various electrical distortions, along with voltage spikes, voltage sags, and so forth. Several innovative techniques were employed for the development of circuits which resulted in minimised voltage stability as well as reliability. Utility companies which are electrical are receiving a large quantity of complaints because of these challenges. An approach is required now to explore the power quality challenges in industrial sector, corporate sector, municipal, or domestic sites. Therefore, a few techniques known as Flexible AC transmission system (FACTs) are used to enhance power quality. It is divided into two categories: namely series-FACTs and shunt-FACTS. As name itself define its architecture that in series-FACTS comprised of transmission line which is connected in series with module and connected in parallel in shun-FACTs. We can alleviate the problems related to power quality with the help of these FACTS devices. D-STATCOM is one of the better devices available. D-STATCOM is a shunt-connected solid-state device employed at the distribution network to maintain load-side disturbances. It has exceeded the traditional capacitor being used improve power quality with it's lower upfront investment, outstanding dynamics, absence of static, and lower operational expenses. The sorts, architectural style, operating, control systems, and AI are all described in this article.

Review on the Performance Evaluation of Thermal Exchangers using Different Baffle Designs

The thermal performance of a heat exchanger depends upon various parameters like inlet temperature of hot fluid, type of hot fluid, type of cold fluid, the shape of baffles, the material of baffles, baffles angle, and property of ribs. Basically fluid flow and heat transfer characteristics largely depend upon the Reynolds number (Re). Reynolds number is basically the ratio of inertia force to viscous force. Re is only the factor by which we can decide whether the fluid is laminar or turbulent in shell and tube type of heat exchanger. The heat exchanger is an adiabatic device in which heat is transferred from one fluid to another fluid across a plate surface. In this paper, we have introduced some special types of triangular baffles with rectangular channels. The purpose of this apparatus is to enhance the performance of the heat exchanger. Heat exchangers, nowadays, are one of the most important heat & mass transfer apparatuses in industries like oil refining; heat treatment plants, electric power generation, etc. are long service life.

Review on the Thermal Performance on the Basis of Different Types of Material used in Ball Bearings

Bearing is a movable object, so frictional forces must be overcome in terms of moving the Bearing. To decrease the friction force on the movable methodology, different kinds of bearings have been used. The bearing gets its characterized by the fact that it is used to support a rotating axle or shaft. Because rolling bearings utilize balls or rollers, they are referred to as "rolling components." one can measure bearing expected lifespan depending on the material exhaustion if one can understand the operations and maintenance of loads and speeds. These computations should be based on the assumption that now the bearing is appropriately installed, lubricated, and moreover treated. It is unable to account for the impact of detrimental operating environment. Damaged bearing has a significant economic and industrial implications.
