Flow Accelerated Corrosion: Forms, Mechanisms and Case Studies

An experimental investigation of mixing mechanisms in shock-accelerated flow

An experimental investigation of mixing mechanisms in a shock-induced instability flow is described. We obtain quantitative two-dimensional maps of the heavy-gas (SF6) concentration using planar laser-induced fluorescence for the case of a shockaccelerated cylinder of heavy gas in air. The instantaneous scalar dissipation rate, or mixing rate, χ , is estimated experimentally for the first time ...

High-temperature ultrasonic thickness monitoring for pipe thinning in a flow-accelerated corrosion proof test facility

In order to monitor the pipe thinning caused by flow-accelerated corrosion (FAC) that occurs in coolant piping systems, a shear horizontal ultrasonic pitch-catch waveguide technique was developed for accurate pipe wall thickness monitoring. A clamping device for dry coupling contact between the end of the waveguide and pipe surface was designed and fabricated. A computer program for multichanne...

Efficient Roof Shapes through Wind Flow and Indoor Temperature, Case Studies: Flat Roofs and Domed Roofs

Comparison of the environmental flow assessment methods involving case studies of Karaj and Talar Rivers

Environmental flow is explained as the period of time, quantity and the amount of required water for maintaining the water, fresh, the river’s ecosystem, human beings’ welfare and the life depending on the water. The main goal of this paper is to investigate and compare the hydrological methods including Tennant, aquatic flow, Tessman, analysis of the flow duration curve and the flow duration c...

Service Discovery Mechanisms: Two Case Studies

Connecting other devices than workstations to the Internet is becoming commonplace now. In this article we investigate two approaches to the discovery of devices and the services they may provide, viz., the Universal Plug ’n Play standard by Microsoft and the wireless Corba model.
