Default Oscillating Pressure Values Rotorblade 2D SST SIM
Posts: n/a
Hi there,

i just finished some 2D SST Simulations of different rotorblade sections (to compare with 3D Result). In general the results in Post "look" good. When i export pressure values along the rotorblade surface (Polyline) to Excel and plotting them over the chord i get oscillating values (small amplitude but clearly visible) near the area of the leading edge. This behaviour is located on suction and pressure side of the blade. When going downstream the values do not show this oscillating behaviour. A friend told me that it is important to activate "Project to BSpline" option in ICEM. I did so but nothing changed.

Any hints? Thanks in advance Kramer
