Numerical solutions and experimental results for three dimensional buoyancy driven flows in tilted cylinders

Finite difference solutions and experiments are presented for free convection in differentially heated cylinders when the inclination varies with respect to the gravity vector. The results are compared with asymptotic solutions in horizontal cylinders for the core- and boundary layer-driven regimes. Over a range of 60° from the horizontal, a good agreement is obtained between the numerical and experimental results for large aspect ratio (A=10)...
