Soret effects on free-convection and mass transfer flow in the stokes problem for a infinite vertical plate
An analytical study is performed to examine the free-convection and mass transfer flow for the Sokes problem for an infinite vertical plate on taking into account the Soret effect (thermal diffusion effect). The Laplace transform technique is used to obtain the expressions for velocity and skin-friction. The effect of Soret numberS on velocity field and skin-friction is extensively discussed with the help of graphs and table.
Decommissioning tasks in laboratories or interim storage facilities may be complicated by poor accessibility and by the diversity of operations that must be carried out. This is particularly true of waste storage shafts that are often accessible only from above and are relatively limited in size compared with existing intervention systems. This article describes the issues involved and the studies that have been carried out to develop a force-feedback Shaft Teleoperation system (STeP). Following a discussion of a range of possible concepts and of the preliminary tests carried out to define the system architecture and functions, the specifications and expected performance of the specially developed master-slave system are described. An example of a waste retrieval application is then presented with emphasis on the tools used and the full-scale mockup that will be built.
