Trying to find any benchmark on the drag coefficient for a cylinder in axial flow. There are many on the flow from the side, also several on axial flow for Re over 10000. What about the near-Stokesian regime?

thank you for the reference. This paper is on the drag force in radial direction, there are multiple similar contributions. I was looking for the drag in AXIAL direction, also when the flow field was not affected by other objects. So the question is still open.
thank you for help! As it follows from the paper, the drag turns to 0 when the cylinder is aligned with the flow. How is it possible?
The behavior depends on the nose shape. The nose may be a cone, a hemisphere, just the blunt face, or in between the latter two. Low-Re drag values may be found in the literature for hypersonic flows where such bodies are used; Re is low in the upper atmosphere. For comparison often the case for Mach=0 is attached.

Hi, thank you all, the answer is found in Fig.4.7 of Clift, Grace and Weber, 1978
