Recently, offshore wind plants, as Horn’s Riv one, have reached a remarkable interest and development. In these sites, HAWT’s blades experiment corrosion, erosion fouling and, at higher latitudes, icing conditions too, in mountainous areas harsch climate sites. The operative may influence the machine damages they occur consequence of erosion, fouling, icing, exfoliation caused by above mentione...

Measurement error due to sensor degradation (fouling, mis-calibration etc.) is more difficult to identify compared to catastrophic sensor failure. Passive methods previously proposed for sensor-level monitoring are based on power spectrum or multi-scale analysis of sensor data. These methods have limitations caused by not accounting for various noise sources, and assumptions about sensor noise ...

The paper describes the development of a supervisory control scheme that adapts to the presence of degradation faults and minimises any resulting increase in energy consumption or deterioration in occupant comfort. Since there is a high degree of uncertainty associated with the results of any fault identi cation scheme in information-poor systems of this type, the supervisory control scheme use...

the effect of membrane molecular weight cut off (mwco) at three levels (10, 20 & 50 kd) on dynamic behavior of permeate flux (jp), hydraulic resistances (total hydraulic resistance, rt; reversible fouling resistance, rrf; irreversible fouling resistance, rif and membrane hydraulic resistance, rm) and milk solutes rejection (protein, rp; fat, rf; lactose, rl; minerals, rm and total solids, r...

As more power generation facilities fall under increasingly strict environmental regulations, many difficult emissions control questions must be answered. In addition, the changes on the electricity market make efficient generation vital if a plant is to remain viable. Until recently an effective method for identifying optimal emissions control technologies has been elusive. Fortunately, emissi...

There is a strong incentive for gas turbine operators to minimize and control performance degradation, as this directly affects profitability. The area of gas turbine recoverable and non-recoverable performance degradation will be comprehensively treated in this tutorial. Deterioration mechanisms including compressor and turbine fouling, erosion, increased clearances, and seal distress will be ...

The Propose of this paper is to introduce a new model for crude oil fouling in preheat trains of crude distillation unit. The experimental results of Australian light crude oil with the tube side surface temperatures between 200-260 oC and fluid velocity ranged 0.25 to 0.4m/s were used. The activation energy of chemical reaction depends on the surface temperature has been calcula...
