| Description |
Fluid Dynamics (CFD) has become largely widespread and accepted as a design tool. In steady simulations industrial strength programs such as Fluent or CFD++ are by now considered a standard.
However in for unsteady problems with complex moving geometries the use of CFD still poses several problems and research is still very active. Amongst these, the problem of moving surfaces is predominant for the design of modern aircrafts and, specifically, the opening/closure of spoiler surfaces is challenging.

The on going research at Politecnico di Milano to develop efficient and accurate schemes continuously sets higher standards, and very promising results have been shown by Flowmesh, the most recent solver developed at DIA. Flowmesh is a finite-volumes solver for the arbitrary Lagrangian-Eulerian (ALE) formulation of the Euler equations that implements a unique strategy that allows to perform adaptive computations without resorting to any interpolation step.
As part of the developing team the student is expected to set-up and run two-dimensional dynamic grid simulations to predict the aerodynamic response for the opening of a spoiler from an airfoil.
|
| Required tasks |
Definition of the geometry of the spoiler and generation of the dynamic mesh that follows the movement of the bodies. Computation of the force and moment coefficients on the airfoil. Parametric study of the effect of the opening time and of the Mach number in terms of the aerodynamic coefficients. Identification of the key parameters to drive solution-based adaptive computations, such as the pressure gradient.
