Effects of hole arrangement and trenched hole on multirow film cooling
نویسندگان
چکیده
Multirow film cooling is an advanced method to provide effective surface for gas turbine components exposed high temperature. In this paper, the performance of multirow under different configurations investigated numerically. The geometrical parameters, including hole arrangement, orientation, and trenched hole, are considered. numerical setup validated before performances compared. flow heat transfer characteristics various analyzed, row-to-row interactions revealed. For with standard holes, staggered arrangement simple angle holes achieves better efficiency than counterpart inline configuration, while opposite compound provides best efficiency. trench promotes coolant uniform mixing, stays more close effusion plate. Thus, holes.

There are issues in organizations that require new theoretical formulation. Hence, metaphorical theorizing is used in the study of organizations to interpret them and understand their complexities. In this method, the organization is likened to an entity and one of the key features of that entity is generalized to the organization. It should be borne in mind that most organizational theories ar...
