Free convection and mass transfer flow of non-newtonian fluid with thermal diffusion effect

An analytical study is performed to examine the thermal diffusion characteristics of free convection and mass transfer flow in a non-Newtonian fluid (Walters, 1962: liquid B') past a uniformly accelerated infinite vertical plate in the presence of thermal diffusion. The expression for the velocity field is obtained by the Laplace transform technique. The influence of the Soret number (a thermal diffusion parameter) on the velocity field is extensively discussed with the help of graphs.     

Adaptive tracking control of an autonomous underwater vehicle

This paper presents the trajectory tracking control of an autonomous underwater vehicle(AUV). To cope with parametric uncertainties owing to the hydrodynamic effect, an adaptive control law is developed for the AUV to track the desired trajectory. This desired state-dependent regressor matrix-based controller provides consistent results under hydrodynamic parametric uncertainties.Stability of the developed controller is verified using the Lyapunov s direct method. Numerical simulations are carried out to study the efficacy of the proposed adaptive controller.     

Free Convection and Mass Transfer Flow of Non-Newtonian Fluid in the Stokes Problem for a Vertical Plate with Thermal Diffusion Effect

An exact analysis of the unsteady free convection and mass transfer flow of non-Newtonian fluid past an impulsively started infinite vertical plate has been presented in presence of thermal diffusion effect. The expression for the velocity field has been obtained by the Laplace transform technique. The influence of Soret number (thermal diffusion parameter) on velocity field is extensively discussed.
