Development and Investigation of Minimum Power Non-contact Swirl Vane Gripper
Abstract: The Swirl vane gripper is a new non-contact gripper, which uses negative pressure created by the air swirling flow to create an upward lifting force. This upward force can be used to lift an object, which is placed underneath the gripper. In comparison with other non-contact grippers, this gripper is electrically actuated (rather than pneumatically) and hence require less power to generate same lifting force as produced by other grippers. …

CONVECTION IN COMPRESSIBLE COUPLE-STRESS DUSTY FLUID
Abstract: The problem of thermosolutal convection in compressible couple-stress fluid in presence of suspended particles is considered. Following the linearized stability theory and normal mode analysis, the dispersion relation is obtained. For the case of stationary convection, the compressibility, couple-stress and stable solute gradient postpone the onset of convection whereas the suspended particles hasten the onset of convection. Graphs have been plotted by giving numerical values to the parameters to depict …
