RISA Streamline Curvature Method for Calculating S1 Stream Surface Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A streamline curvature method for calculating S1 surface flow in turbines is presented. The authors propose a simple method in which a domain of calculation can be changed into an orderly ...
Performance and Kinetics of Aerated Fluidized Bed Biofilm Reactor
Publisher: American Society of Civil Engineers
Abstract: The aerated fluidized bed biofilm reactor (FBBR) was evaluated for treatment of a corn starch wastewater at food‐to‐microorganism (F/M) ratios ranging from 0.42 to 1.61 g 5‐day biochemical oxygen demand
Effect of Slowly Biodegradable Organics on Kinetic Coefficients
Publisher: American Society of Civil Engineers
Abstract: Measurement of both soluble COD and BOD on activated sludge effluent reveals that effluent organic matter contains a significant quantity of slowly biodegradable organics. These slowly degradable organics exhibit a significant ...
An Active Roll Mode Suspension System for Ground Vehicles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes an automatic roll mode control system for ground vehicles. The primary objective of the so-called “active suspension system” is to maintain a coordinated vehicle banking ...
Measurements of Heat Transfer Coefficients and Friction Factors in Rib-Roughened Channels Simulating Leading-Edge Cavities of a Modern Turbine Blade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Leading edge cooling cavities in modern gas turbine blades play an important role in maintaining the leading edge temperature at levels consistent with airfoil design life. These cavities often ...
Experimental Study of the Effects of Bleed Holes on Heat Transfer and Pressure Drop in Trapezoidal Passages With Tapered Turbulators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Trailing edge cooling cavities in modern gas turbine blades often have trapezoidal cross-sectional areas of relatively low aspect ratio. To enhance cooling effectiveness in these passages, they ...
Darryl E. Metzger Memorial Session Paper: Experimental Heat Transfer and Friction in Channels Roughened With Angled, V-Shaped, and Discrete Ribs on Two Opposite Walls
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental investigations have shown that the enhancement in heat transfer coefficients for air flow in a channel roughened with angled ribs is on the average higher than that roughened with ...
Measurements of Heat Transfer Coefficients and Friction Factors in Passages Rib-Roughened on All Walls
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A liquid crystal technique was used to measure heat transfer coefficients in twelve test sections with square and trapezoidal cross-sectional areas representing blade midchord cooling cavities in ...
Chemical/Bio‐fluidized Bed Treatment of Slaughterhouse Wastewater
Publisher: American Society of Civil Engineers
Abstract: A combined chemical coagulation/flocculation‐Fluidized Bed Biofilm Reactor (FBBR) process was evaluated for the treatment of an equalized slaughterhouse wastewater. Results obtained from jar and tank tests indicated that ...
Prediction Model for Failure Pressure of Large-Diameter Gas Pipelines at Different Temperatures
Publisher: ASCE
Abstract: Long-distance gas pipelines in service inevitably are exposed to harsh conditions such as extreme temperature. It is also recognized that corrosion is one of most influential factors on the structural reliability and safety ...
