Investigation of Impingement Heat Transfer of Single Hole in a Limited Space

On the basis of the similarity theory,the local impingement heat transfer coefficient of a single hole impinging on a plate in a limited space was studied with constant heat flux methods.The relationship of various flow and structure parameters with the impingement heat transfer coefficient was summarized,also the fitting equations of average impingement heat transfer coefficient were given according to the linear simulation.The results could be useful for the engineering design and scientific research.
