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.

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.
