Comparison of RCC Buildings with a Soft Storey Irregularity in Different Zones

Soft storey is one of the main reasons for building damage during an earthquake and has been mentioned in all investigation report. Soft storeys in a high rise building play an important role on its seismic performance. At the soft storey level, there is a discontinuity in the rigidity of the structure due to lack of infill walls or due to variation in floor height. Soft storey is generally utilized as a part of auxiliary individuals in a building. Ex cellar stopping, shops. soft story is floor level in which the stiffness of the floor is under 80 of the normal stiffness of three stories above it. Earthquake occurred in multi storeyed building shows that if the structures are not well designed and constructed with an adequate strength it leads to the complete collapse of the structures. To ensure safety against seismic forces of multi storied building, there is need to study of seismic analysis to design earthquake resistance structures. Building irregularities generally become obvious with the effect of a seismic load. It is crucial that the irregularities of structural systems should be considered properly with respect to the conditions determined by the building codes.

Effect of Dimple Protrusion Shape on The Cooling Performance of The Turbine Blade Using CFD

It is well understood that one way to improve a gas turbine engines power output and thermodynamic performance is to increase the temperature of the turbine inlet TIT . The inlet temperature should be gradually elevated to higher targets to pursue greater control. However, with the rise in blade inlet temperature, the heat applied to the blade increases, and the permissible melting temperature of materials increases at a slower rate. This implies that the inlet temperature of the turbine blade will exceed the melting temperature of the material by more than 500 . Thus, cooling turbine blades for a safe and long lasting operation is important. To lower the temperature of the blade content below its melting point, different internal and external cooling techniques are employed. . In recent years, in the tip region of the turbine blade, multiple augmentation devices such as fins, ribs, pins, and dimples protrusions have gained a lot of attention to enhance heat transfer. With increasing inlet temperature of the turbine, pin fin arrays cannot satisfy the need of the cooling alone. To be paired with the pin fin arrays, several more methods are also added. With slight loss of pressure, dimples and protrusions are fine options. In this present work, the numerical approach is used to investigate the influence of dimples or protrusions shape on the cooling of the turbine blade. The ANSYS 17.0 simulation software was used. The results of this study show that the , due to flow acceleration, increase in impingement area and shrinkage of the flow recirculation region within the dimple, pin fin dimple wedge duct with triangular shape dimples protrusions provides improved heat transfer enhancement.

A Review Paper on Gas Turbine Blade Cooling Methods

For aircraft propulsion, land based power generation, and other industrial applications such as trains, marines, automobiles, etc., gas turbines are commonly used. The operating temperature must be raised to increase the thermal performance and output work of the gas turbine engine to accommodate the accelerated production of modern gas turbines. The heat transmitted to the turbine blade, however is greatly increased as the temperature of the turbine inlet is constantly increased. For a long service life and healthy running, it is also very important to cool the turbine blades. Currently available methods for cooling turbine blades include film cooling with impingement cooling for the front edge, turbulent rib cooling with serpentine passages for the middle section of the blade, and pin fin cooling for the trailing edge of the turbine blade. The cooling system for turbine blades must provide cooling for all potential regions that are subjected to hot gas flow. This paper provides a literature review of blade tip leakage and heat transfer, as well as studies into external and internal cooling technologies.

Digital Marketing Features

The article analyzes the peculiarities of digital marketing the definition of digital marketing, the advantages and disadvantages of digital marketing, the process of digital marketing. Digital marketing is an important stage in business planning, during which a strategy is developed that can help make the business much better known and at the same time sell much more goods or services. Digital marketing helps to increase brand awareness as interest in social networks, email marketing, content marketing grows every year. Digital marketing can be defined as the process by which the mayor strives to better understand customers and at the same time find out if the goods and services offered are suitable for the market.

Relation between Area of Opening and Range of Splash of Testing Fluid during Hydro Testing of Knife Gate Valve

Determination of relations between various variables is necessary while designing any experiment. Various methods may be employed depending on the availability of resources at the experimental setup. However, while the experiment is being designed, it is equally important that the same is backed by theoretical formulae. If not derived or proved already, new ones can definitely be derived using first principles. In this study, a relation between the area of opening and range of splash shall be derived. The aim of this relation shall be to get a basic comprehension of the variation in parameters in relation to the range of splash of testing fluid. The concepts of range of splash and area of opening shall be reported at the initial stage. The area of opening shall then be determined using the method of integration considering variables involved in the formulation. On obtaining an expression, a relation between the area of opening and the range of splash shall be derived. Towards the end a conclusion shall be drawn reporting the proportional relations between the variables.

Regular Human Capacity Building Programme A Tool for Quality Teachers’ Productivity in Public Secondary Schools in Bayelsa State

This study examined the type of human capacity building programmes available for teachers, how often teachers’ developmental programmes are organized and teachers’ perceived benefits of self capacity development programmes. A descriptive research design was adopted with a total of 110 teachers from government owned secondary schools in Kolokuma Opokuma Local Government Area of Bayelsa State made up sample size. Three research questions and three hypotheses guided the study. The instrument used for data collection was 21 item structured close ended questions tagged “Questionnaire on Human Capacity Building Programmes for Quality Teachers Productivity QHCBPQTP developed using the modified Likert scale format. Cronbach Alpha technique yielded an internal consistency of 0.92 for the instrument. Mean and standard deviation were used to analyze the research questions while z test was used to test the null hypotheses at 0.05 level of significance. The findings concluded that all teachers of government owned public secondary schools in Kolokuma Opokuma Local Government Area of Bayelsa State do not go through capacity building programmes for training and retraining via workshops, seminars etc to update their knowledge as they become obsolete using outdated methods of teaching and classroom management. The findings also revealed that teachers who go through self capacity development programmes are not recognized thereby discouraging other teachers for developing themselves. It was therefore recommended that the government should regularly organize, workshops, seminars, conferences for teachers to update teachers’ knowledge in human capacity professional building development programmes to enhance quality productivity.
