Investigating the Dehumidification Characteristics of Turbine Stator Cascades with Parallel Channels

Parallel Computation of Stator-Rotor Interaction in an Axial Turbine

The unsteady flow caused by the interaction of guide vanes and runner is investigated for an axial turbine. The calculation is performed in parallel. The solution algorithm and the parallelization procedures are described. The parallelization is obtained by domain decomposition with overlapping meshes. The interaction of rotor and stator is handled by a sliding interface where downstream the no...

the evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology

abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...

determination of maximal singularity free zones in the workspace of parallel manipulator

due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
