The impinging solar receiver, bearing the merits of high heat transfer coefficient and compact structure, has a great potential in the field of solar dish Brayton system. Despite the wide application of cylindrical structure in the impinging solar receiver, the research on orifice array optimization against curvature surfaces is rare.In this paper, the main objective is to study the heat transfer and pressure drop characteristics of an orifice impinging array under a constant mass flow rate and a constant surface temperature boundary condition for the future impinging receiver design. Various orifice shapes were studied via numerical tools (Ansys Fluent 14.0) and their performances in both pressure drop and heat transfer coefficient were compared. The upstream fillet orifice was found to have the lowest pressure drop with moderate compromise in heat transfer coefficient. Moreover, a mathematical optimization model, based on empirical correlations, was developed for the orifice impinging array on the convex cylindrical surfaces. This model can provide an appropriate range of orifice number and orifice diameter, from which the key factors of the array including the ratio of height and orifice diameter H/D, orifice interval, number of orifices in each tier circumferential and tier numbers can be calculated. Several validation cases were also conducted by Ansys Fluent
