Detailed Description

Process generating divergence-free correlated noise, imposing no-penetrability condition on bluff bodies, preserving boundary conditions on boundaries and (if required) adding the contribution of a manually-loaded velocity field.

The generated initial field reads u_0 = u_T + c*P(u_{cn}) + c*\nabla potential , where u_T is the velocity field we load, c a penalty coefficient, and P(u_{cn}) and \nabla potential are discussed next. The process first projects the correlated noise u_{cn} into the model part. The projected correlated noise is denoted as P(u_{cn}). Then, the associated poisson problem for the unknown TEMPERATURE is solved:

• \nabla \cdot \nabla TEMPERATURE = \nabla \cdot (c*P(u_{cn}) + u_{T}) on \Omega c*P(u_{cn}) \cdot NORMAL = - \nabla TEMPERATURE \cdot NORMAL on \partial \Omega_{bluff body} TEMPERATURE = 0 on \Omega_{outlet} Then, the tangential velocity is set to zero on the boundaries \partial \Omega_{bluff body} and \partial \Omega_{external domain} by doing: P(u_{cn}) + \nabla TEMPERATURE = 0 on \Gamma The correlated noise satisfying the no-penetrability and solenoidal conditions and respecting the boundary conditions is: VELOCITY = u_T + c*P(u_{cn}) + c*\nabla TEMPERATURE.
