Turbines and compressors are examples of turbomachinery, which transfers energy between a rotor and a fluid. A compressor transfers energy from a rotor to a fluid, whereas a turbine transfers energy from a fluid to a rotor. Turbomachinery devices are found in many applications from different industries as fans, pumps, propellers, compressors and turbines. Regarding flow characteristics, it is convenient to make the distinction between low-Mach and high-Mach turbomachinery devices to understand the actual applications. Computational fluid dynamics (CFD) plays an essential role to analyze fluid flows and heat transfer situations.
Turbine fouling in gas turbine systems can cause significant losses in power and efficiency. The water coverage system is used to remove deposits without turning off the gas turbine.
This process uses ANSYS Fluent with RNG k-epsilon, droplet evaporation and wall-film modeling for consideration with limited multi-purpose optimization. To develop a design plan for selecting the optimal nozzle diameter, location, mass flow rate and full cone nozzle angle for Mitsubishi MW701D gas turbine power plant.
We applied the finite element method and computational fluid dynamics to solve a housing damage problem of a compressor blade. The simulation results show airflow, temperature, pressure, safety factor, and life in the compressor stage. We proposed the proper shape of the compressor blade not only can be solved the problem, but also help to extend the maintenance period of EGAT.
