Similarity solutions in axisymmetric mixed-convection boundary-layer flow (Q1110415)

The authors consider the similarity equations for mixed-convection axisymmetric boundary layer flow. The solution of the problem is obtained numerically and it has been shown that for large buoyancy parameter (\(\alpha)\) and curvature parameter (\(\beta)\) of O(l), an asymptotic solution is approached, the nature of which is discussed. It has also been shown that when \(\beta\) is also large, of \(O(\alpha^{1/4})\), the problem, at leading order, becomes independent of the main stream and the free convection limit obtained. Some special cases are also discussed.
