The paper describes a numerical technique for the design and the analysis of the flow in air intakes and nozzles. The interaction with the external flow and lesson learned in shape optimization are both concerned in an unified approach which refers to the solution of an inverse problem. The unsteady Euler equations are integrated numerically by using a time-dependent procedure and by adopting an upwind finite volume approximation. Several numerical examples of increasing complexity are presented. The design concept is thought here as an integrated design in which the nozzles and intake are a part truly dialing with the system as a whole.

Abstract
The paper describes a numerical technique for the design and the analysis of the flow in air intakes and nozzles. The interaction with the external flow and lesson learned in shape optimization are both concerned in an unified approach which refers to the solution of an inverse problem. The unsteady Euler equations are integrated numerically by using a time-dependent procedure and by adopting an upwind finite volume approximation. Several numerical examples of increasing complexity are presented. The design concept is thought here as an integrated design in which the nozzles and intake are a part truly dialing with the system as a whole.Pubblicazioni consigliate
