RISIntegral Design of a Turbocharger for Internal Engine Energy Saving: Centrifugal Compressor Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Energy savings and emission reductions are essential for internal engines. Turbocharger is critical for engine system performance and emission. In this study, the engine simulation program was used to systematically optimize ...
Effects of Asymmetric Radial Clearance on Performance of a Centrifugal Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The centrifugal compressors are widely used in industrial applications. The design, manufacturing, and installation are all critical for the compressor performance. Many studies have been carried out in the past to optimize ...
Transient Behavior of Glow Plugs in Direct-Injection Natural Gas Engines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Glow plugs are a possible ignition source for direct injected natural gas engines. This ignition assistance application is much different than the cold start assist function for which most glow ...
Safety Assessment of Cold Welding Defect in Electro Fusion Joint of Polyethylene Pipe
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cold welding defect is the most common defect in electrofusion (EF) joint for connecting polyethylene (PE) pipe. In our previous study [1], the cold welding defect is successfully inspected by an eigenline method based on ...
Performance Optimization of the High-Pressure Compressor in Series Two-Stage Turbocharging System Based on Low-Speed Performance Requirements of Diesel Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The performance of the high-pressure (HP) compressor is very important for the two-stage turbocharging system. However, the performance of HP compressor on the engine most of the time is poor at low speed and low mass flow ...
Estimation of Uncertainty in Temperature Observations Made at Meteorological Stations Using a Probabilistic Spatiotemporal Approach
Publisher: American Meteorological Society
Abstract: probabilistic spatiotemporal approach based on a spatial regression test (SRT-PS) is proposed for the quality control of climate data. It provides a quantitative probability that represents the uncertainty in each temperature ...
Interpolation of Missing Temperature Data at Meteorological Stations Using P-BSHADE
Publisher: American Meteorological Society
Abstract: ome climate datasets are incomplete at certain places and times. A novel technique called the point estimation model of Biased Sentinel Hospitals-based Area Disease Estimation (P-BSHADE) is introduced to interpolate missing ...
Design and Analysis of Energy-Efficient Low-Flow Centrifugal Compressors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With the increasing demands of energy-saving from industries, the low-flow coefficient and low specific speed centrifugal compressors have gained more attention. The design of this type of compressor faced many challenges, ...
Influence of Architectural Facades on Wind Pressures and Aerodynamic Forces of Tall Buildings
Publisher: ASCE
Abstract: Architectural facades including balconies, mullions, shading boards, and ribs are widely used outside of tall buildings for the purpose of aesthetics and function. And these facades will affect the wind loads of tall ...
Measurement While Drilling Method for Estimating the Uniaxial Compressive Strength of Rocks Considering Frictional Dissipation Energy
Publisher: American Society of Civil Engineers
Abstract: Relationships between drilling parameters and the uniaxial compressive strength (UCS) of rocks are typically established through measurement while drilling (MWD) by analyzing either drilling speed or specific energy. This ...
