HI(adsbygoogle = window.adsbygoogle || []).push({});

i have been involved with a problem which requires me to calculate the drag of a finite circular cylinder of very low aspect ratio (~1.2) i.e the h/d= 1.2

The Re_{d}= 5.4x 10^{5}(based on diameter)

and the Re_{x}= 8.46x 10^{6}

The flow regime is very low subsonic ( M=0.15)

I need to predict the drag contribution of this body on an a/c

I have gone through various ESDU( 83025 and 80025) and an AGARDDoc Aircraft Excrescence Drag by A D Young, but to no help as these do not contain the flow regime i am aiming at.

I would like help with respect to above problem regarding that someone could point me out in the right direction as to where to look or whether i need to look only for 2D cases here as the aspect ratio is so low.
