An analytical and experimental work is described on natural convection in an inclined cylindrical annulus enclosed in heated inner and cooled outer cylinders. Three-dimensional governing equations are transformed into the finite-difference equations and solved numerically using the successive over-relaxation (SOR) procedure. The three-dimensional structure of the fluid flow and temperature distributions as well as Nusselt numbers are obtained and the effect of inclination on them is examined. A flow visualization experiment using a tracer technique is conducted; photographs of streaklines confirm the three-dimensional flow structure obtained analytically.
