RISComputational Fluid Dynamics Thermohydrodynamic Analysis of Three Dimensional Sector Pad Thrust Bearings With Rectangular Dimples
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper presents a detailed computational study of flow patterns and performance indices in a dimpled parallel thrust bearing. The bearing consists of eight pads; the stator surface of each pad is partially textured with ...
Numerical Simulation of Three Dimensional Flow Past a Cylinder Oscillating at the Strouhal Frequency
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper presents computational results of 3D flow past a cylinder forced to oscillate: (a) transversely with respect to a uniform stream and (b) both transversely and inline with respect to a uniform stream, following a ...
Hydrodynamic Forces and Flow Structures in Flow Past a Cylinder Forced to Vibrate Transversely and Inline to a Steady Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper reports computational results of forces and wake structure in twodimensional flow past a circular cylinder forced to vibrate both transversely and inline to a uniform stream, following a figureeight trajectory. ...
Development and CFD Validation of an Integrated Model for Marine Heavy Fuel Oil Thermophysical Properties
Publisher: American Society of Civil Engineers
Abstract: The paper presents a new integrated model for calculating the thermophysical properties of marine heavy fuel oil (HFO). The model considers HFO as an equivalent one-component heavy petroleum fraction with undefined composition ...
Development of an Experimentally Validated CFD Engineering Tool for Marine Engine Applications
Publisher: American Society of Civil Engineers
Abstract: AbstractMarine engine development is undergoing a challenging transition, dictated by the
decarbonization frame set by the International Maritime Organization (IMO). In this
context, new fuels, such as methanol and ammonia, ...
Tribological Optimization of Thrust Bearings Operated With Lubricants of Spatially Varying Viscosity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the present work, a computational optimization study of thrust bearings lubricated with spatially varying viscosity lubricants is presented, with the main goal of minimizing friction coefficient. In practice, spatial ...
