Hello,

i am currently working on a quite simple fluent simulation, with a steady water stream and a 1m-diameter sphere in the middle of the stream. My goal is to reach the known drag coefficient an drag force values for the sphere just to get some validation for a more complicated simulation i am working on. But actually the solutions i get in my fluent simulations are very different then what i found in the literature. I chose the k-omega SST viscous model for the simulation. I did also set the reference values and generated a fine mesh.

I created a little table with the values i got from my simulation and the literature i found. The Table is in the attachments.

Does anyone know where the problem might be or what i am doing wrong ? Thanks for every help.
