RISNumerical Solution of Inviscid Two-Dimensional Transonic Flow Through a Cascade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper presents a method of numerical solution of transonic potential flow through plane cascades with subsonic inlet flow. The problem is formulated as a weak solution with combined Dirichlet’s ...
A Statistical Approach to Spark Advance Mapping
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Engine performance and efficiency are largely influenced by combustion phasing. Operating conditions and control settings influence the combustion development over the crankshaft angle; the most ...
Spark Advance Real-Time Optimization Based on Combustion Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: One of the most effective factors influencing performance, efficiency, and pollutant emissions of internal combustion engines is the combustion phasing: In gasoline engines, electronic control units ...
A New Approach to Evaluate the Cavitation Erosion Power
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The dynamic response of various materials exposed to liquid jet and pressure wave impacts was simulated making use of an elastoplastic solid model. Numerical pit profiles were compared to ...
Hydrostatic Retesting of Existing Pipelines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An analytical model is presented for predicting hydrostatic retest intervals in liquid pipelines which are subjected to frequent large pressure cycles. The model utilizes pressure cycle history, ...
A Computational Investigation of the Steady State Vibrations of Unbalanced Flexibly Supported Rigid Rotors Damped by Short Magnetorheological Squeeze Film Dampers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Unbalance is the principal cause of excitation of lateral vibrations of rotors and generation of the forces transmitted through the rotor supports to the foundations. These effects can be significantly reduced if damping ...
Evaluation of the Effect of Misalignment and Profile Modification in Face Gear Drive by a Finite Element Meshing Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Face gear drives have many advantages over other cross axis transmissions especially in high performance applications. The lack of published design experience and design standards make their ...
Advances in Finite Element Simulations of Elastosonography for Breast Lesion Detection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Among the available tools for the early diagnosis of breast cancer, the elastographic technique based on ultrasounds has many advantages such as the noninvasive measure, the absence of ionizing ...
The Effect of Voltage Polarity on Ice Accretions on Short String Insulators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present study investigated the effect of voltage polarity on ice deposits accumulated on a short-string of porcelain insulators from 85 μm supercooled droplets in a cold room maintained at ...
Analytical Modeling of Self-Loosening of Bolted Joints Subjected to Transverse Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Self-loosening of bolted joints is a common issue in structural connections and machine design. This phenomenon can not only cause the industry a lot of losses due to maintenance but can result in catastrophic incidents ...
