We propose a 3D meshless method to compute mean pressure fields in turbulentflows from image velocimetry. The method is an extension of the constrainedRadial Basis Function (RBF) formulation by \citet{Sperotto2022} to a ReynoldsAveraged Navier Stokes (RANS) framework. This is designed to handle bothscattered data as in Particle Tracking Velocimetry (PTV) and data in uniformgrids as in correlation-based Particle Image Velocimetry (PIV). The RANSextension includes the Reynolds stresses into the constrained least squareproblem. We test the approach on a numerical database featuring a BackwardFacing Step (BFS) with a Reynolds number of 6400 (defined with respect to theinlet velocity and step height), obtained via Direct Numerical Simulation(DNS).
