Description
Description
The present problem simulates the Cooling of Turbine Blade by ANSYS Fluent Turbine. We perform this CFD project and investigate it by CFD analysis.
To simplify the problem model, considering the symmetrical structure of the turbine body and its blades, only one blade is simulated. The main purpose of the problem is to investigate the temperature distribution and changes in thermal energy on the body and turbine blade.
Therefore, the process of simulating the model and defining the boundary conditions of the model is performed in such a way that the fluid behavior is focused on heat transfer.
The cooling process in this model is based on the definition of cool airflow in an empty space in the inner walls of the blade. These inner walls have a series of holes to increase the contact surface with the cold flow and thus increase the cooling process.
The present 3-D model is drawn using the CATIA software and then imported into the Design Modeler software. The meshing of the present model has been done using ANSYS Meshing software. The mesh type is unstructured and the element number is equal to 10154723.
Turbine Blade Methodology
The boundary condition of heat transfer has been used on the surfaces of the outer and inner walls of the blade. The outer surface of the blade and its lower body, which are under the hot working airflow of the system, have a transfer coefficient of 200 watts per cubic meter and a temperature of 1672 Kelvin.
However, the inner surface of the blade, which is cooled by the cold airflow, has a heat transfer coefficient of 200 watts per cubic meter under a cold flow of 300 Kelvin.
Turbine Blade Conclusion
After the solution process is complete, 2-D and 3-D temperature contours are obtained in the space between the outer wall of the blade (in contact with the hot flow) and the inner wall of the blade (in contact with the cooling flow).
Also, the amount of heat transfer coefficient is obtained on the inner and outer walls of the blade and the blade base.
The two-dimensional contours in the XZ section are drawn at different distances of 0.004, 0.016, 0.028 and 0.04 meters from the upper surface of the blade base, as well as in the XY section at different distances
