Natural Convection Heat Transfer from an Inclined Cylinder

arXiv:2512.06019v1 Announce Type: new
Abstract: This investigation derives a novel formula predicting the natural convective heat transfer from an inclined cylinder given its length, diameter, inclination angle, Rayleigh number, and the fluid’s Prandtl number and thermal conductivity.
The present formula was tested with 93 inclined cylinder measurements having length-to-diameter ratios between 1.48 and 104 in nine data-sets from three peer-reviewed studies, yielding (data-set) root-mean-squared relative error values between 1.6% and 4.7%.
