UPCYCLING OBSOLETE MECHANICAL EQUIPMENT INTO INNOVATIVE LABORATORY TEST RIGS: A LOW-COST SOLUTION OR A SUSTAINABLE DESIGN APPROACH?

Is This a Bug or an Obsolete Test?

In software evolution, developers typically need to identify whether the failure of a test is due to a bug in the source code under test or the obsoleteness of the test code when they execute a test suite. Only after finding the cause of a failure can developers determine whether to fix the bug or repair the obsolete test. Researchers have proposed several techniques to automate test repair. Ho...

Design of Web-based Real-time Control Laboratory for Diversely Located Test Rigs

This paper introduces a four-layer structure for the global scale remote laboratory NCSLab (www.ncslab.net) which provides a unified interface for accessing the test rig diversely located. This structure is good for both expansion and maintenance. All the test rigs are classified into several sublaboratories according to their functions rather than their locations. The user doesn’t have to know...

A Low Cost Numerical Simulation of a Supersonic Wind-tunnel Design

In the present paper, a supersonic wind-tunnel is designed to maintain a flow with Mach number of 3 in a 30cm×30cm test section. An in-house CFD code is developed using the Roe scheme to simulate flow-field and detect location of normal shock in the supersonic wind-tunnel. In the Roe scheme, flow conditions at inner and outer sides of cell faces are determined using an upwind biased algorithm. ...

Mechanical Design of Mixing Equipment

Mixing equipment must be designed for mechanical and process operation. Although mixer design begins with a focus on process requirements, the mechanical design is essential for successful operation. Usually, a competent manufacturer of mixing equipment will take responsibility for the mechanical design. However, process conditions, such as impeller operation near a liquid surface, can impose s...
