Study of Rotor Tip-Clearance Flow Using Large-Eddy Simulation

A large-eddy simulation has been performed to study the temporal and spatial dynamics of a rotor tip-clearance flow, with the objective of determining the underlying mechanisms for low pressure fluctuations downstream of the tip-gap. Simulation results are compared with experimental measurements, and favorable agreements are observed in both qualitative and quantitative sense. Typical vortical ...

Computational Investigation on Deswirl Vanes for Multistage Centrifugal Compressors

The goal of this project is to report on some computational investigations about the return flow passages. The return flow channel provides the connection and carries the flow between two stages of a multistage centrifugal compressor. Of course, deswirl vanes are indispensable between the inlet and outlet section, because usually the inlet flow angle, which comes from the impeller, is 70◦ − 75◦...

Experimental Investigation of Factors Influencing reworks in Construction

Rework in construction project is referred to as an unnecessary effort of redoing a process or activity that was incorrectly implemented in the first instance. In constructions, rework can result from an array of factors such errors, omissions, failures, changes, poor communication. In this paper, the significance of reducing rework and overrun cost due to rework has been arrived.
