System and method for measuring cooling of a component |
| 摘要 |
A system and method for measuring cooling effectiveness of a component is disclosed. The method includes providing a component having a surface provided with a coating including a volatilization-susceptible constituent and a volatilization-resistant constituent. Further, the method includes supplying a first gaseous medium over the surface of the component through a plurality of holes in the component and feeding a second gaseous medium along the surface of the component. The method includes exposing the surface of the component to the first and second gaseous mediums for a predetermined period. The method further includes determining a thickness of the coating exposed to the flow of the first and second gaseous mediums. The method includes analyzing the thickness of the coating to determine whether the coating is removed from the surface of the component upon exposure to the first and second gaseous mediums. |

1. A method for measuring cooling effectiveness of a component, the method comprising:
providing the component having a surface provided with a coating including a volatilization-susceptible constituent and a volatilization-resistant constituent; supplying a first gaseous medium from a first source, through a plurality of holes in the component, for forming a cooling film of the first gaseous medium on the surface; feeding a second gaseous medium from a second source, along the surface of the component; exposing the component to a flow of the first and second gaseous mediums for a predetermined period; determining a thickness of the coating exposed to the flow of the first and second gaseous mediums from a measurement device; and analyzing the thickness of the coating to determine whether at least a portion of the coating is removed from the surface of the component upon exposure to the first and second gaseous mediums for the predetermined period, wherein a removed thickness of the coating is indicative of an ineffectively film cooled region on the surface of the component and a retained thickness of the coating is indicative of an effectively film cooled region on the surface of the component. |
