Abstract
The behaviour of an isolated dislocation in a Rayleigh-Benard roll structure is studied within a linear elasticity theory of topological defects on a model which includes the effect of a large-scale drift flow. The climb velocity is given as a function of the Prandtl number, Rayleigh number and wavenumber for both rigid and stress-free boundary conditions. The effect of a lateral boundary is also briefly discussed.Keywords
