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 […]
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 […]
Comparison of Strength Characteristics of Concrete by using Fly Ash and Rice Husk Ash
A state of extreme landfill areas redevelopment program in many parts of the country has cause to bring the use of recycled aggregate. The low quality of recycled aggregate has limited its use to low grade applications such as roadwork sub base and pavements, while its adoption for higher grade concrete is rare because of […]
Design and Analysis of Hook Nut for a 75 Tonne EOT Crane
Electric Overhead Travelling EOT Crane is used to carry a heavy load in the industry. Due to the convention of heavy metal sat very high temperature, a Foundry requires cranes to transfer loads from one point to another. This makes the EOT cranes most widely and extensively used element in the industry. Every year the […]
What Constrains Smallholder Farmers Decisions to Participate and use Agricultural Value Chain Financing in Rwanda The Case of Smallholder Potato Farmers in Musanze and Nyabihu Districts
Smallholder farmers contribute more to food security and poverty reduction in Rwanda. However, lack of agricultural finance is one of numerous challenges they face for improving productivity and increasing income along the value chain. The objectives of this paper were to determine the factors influencing the farmers’ decision to participate and use agricultural value chain […]
