in this paper, the fluid-structure interaction phenomenon and the research history are described. then due to the complex and specific working conditions of a turbine blade, we have investigated the phenomenon on this subject. the fluid-structure interaction on a turbine blade model has been simulated by using structural and fluid flow section of ansys software. a model of turbine blade with ai...

Increasing the gas temperature at inlet to high pressure turbine of engines is known as a proven method increase efficiency these engines. However, this will expose blades’ surface very heat load and thermal damages. In case un-shrouded blades, blade tip be exposed significant due developed leakage flows in gap, leads in-service burnout which degrades shortens its operational life. This paper s...

Turbine is the most important part of hydro power plant which converts the potential energy of water into mechanical energy. The presence of silt in water erodes the turbine material. Erosion of turbine decreases the performance of turbine, life of the turbine as well as loss of power generation. This paper presents a new approach for the study of silt erosion of hydro turbine. In this study, w...

A power criterion for selecting the electric motor used in a gas turbine emulator is defined. The power criterion is derived in terms of the ratio of inertias between the gas turbine engine and the electric motor, rotational losses and load torque. The gas turbine emulator allows emulating the speed-torque behavior of a gas turbine engine. Using simulation models, we show that the steady-state ...

The Output power of wind turbine is determined by wind speed. The Output power can be adjusted by controlling the generator speed and pitch angle of wind turbine. When the wind speed below the wind turbine rated, the output power of generator can be maximized by controlling the generator speed at point of maximum power coefficient. When the wind speed above the wind turbine rated, output power ...

Combined Cycle Gas Turbine (CCGT) integrates two cyclesBrayton cycle (Gas Turbine) and Rankine cycle (Steam Turbine) with the objective of increasing overall plant efficiency. In modern gas turbine the temperature of the exhaust gases is in the range of 500 oC to 550 oC. Modern steam power plants have steam temperature in the range of 500 oC to 630 oC. Hence gas turbine exhaust can be utilized ...
