The document summarizes an experimental investigation of convection heat transfer for laminar flow in an inclined annulus. An annular copper pipe was exposed to a constant heat flux and rotated through inclination angles from 0° to 90° in 10° increments. Results showed that the heat transfer coefficient decreased inversely with inclination angle, with a maximum 6.6% reduction at 90°. Reynolds number also decreased inversely with angle from 1750 to 1700. Experimental results closely matched a correlation up to 40° inclination. The study found inclination angle had a small effect on heat transfer for laminar flow in the annulus.
