METHODS AND SYSTEMS FOR OPTIMISING THE DESIGN OF AERODYNAMIC SURFACES

摘要

Methods and systems for optimising the design of aerodynamic surfaces. They include in the design process of the aerodynamic surface of a body (41) which moves through a flow field, the following steps: a) preparation of a CFD simulation of said body (41); b) resolution of the CFD calculation for specific conditions of the flow field and for obtaining the flow lines (51) of the flow on said surface; c) calculation of at least one geometrical variable of the surface such as the normal curvature, according to the direction of said flow lines (51) and additionally at least one relevant variable of the aerodynamic flow, such as the pressure gradient; d) simultaneous visualisation of the surface of said body (41) and of at least one geometric variable and, additionally, said at least one variable of the aerodynamic flow.
