ANSYS Fluent Tutorial: Lateral Hole Air Inlets Cooling of Airfoil Surface

The current issue models the movement of hot airflow across the surface of an airfoil and Cooling of Airfoil Surface using lateral air inlets with ANSYS Fluent software. This CFD study and investigation are carried out by us.

In jet engines, surface cooling of airfoils has emerged as one of the most crucial concerns in mechanical engineering and aerospace.

Using Design Modeler software, the current model is three-dimensionally constructed. Ansys Meshing tool has produced the meshing of this current model. There are 582263 total cells.

Cooling Techniques

ANSYS Fluent software simulates in this project the movement of hot airflow across the surface of an airfoil and the surface cooling of the said airfoil utilizing lateral hole air inlets.

The heated air enters the computational domain with a velocity and temperature of 15 m/s in the X direction and 600 K, respectively. The surface cooling of the blade or airfoil is caused by two lateral air inlets.

These cooling inlets also let the air in at 6.59 m/s and 300 K. Turbulent flow equations are solved using the standard k-epsilon model; the Energy equation is turned on to determine the temperature distribution inside the computational domain.

Final Cooling

We get two-dimensional contours connected to pressure, velocity, and temperature at the conclusion of the solution procedure. The injection of cold airflow makes clear the temperature drop close to the surface of the airfoil.

Moreover, since the free stream has a temperature of 600 K and the blade's final temperature is under 520 K, it can be seen in temperature contour and blade temperature change with respect to blade position diagram that the lateral inlets have efficiently performed their function and reduced the temperature of the blade's surface.
