RISResearch on Mechanism of Dynamic Evolution Vibration Characteristics of Horizontal 90 Deg Elbow Flow Pattern
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pipeline vibration induced by fluid flow can cause pipeline fatigue damage, which seriously endangers the safety of the operation. This paper aims to clarify the dynamic variation law of pipeline vibration induced by ...
Hydrodynamic Effects on Particle Deposition in Microchannel Flows at Elevated Temperatures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Particulate fouling and particle deposition at elevated temperature are crucial issues in microchannel heat exchangers. In this work, a microfluidic system was designed to examine the hydrodynamic effects on the deposition ...
Infarcted Left Ventricles Have Stiffer Material Properties and Lower Stiffness Variation: Three Dimensional Echo Based Modeling to Quantify In Vivo Ventricle Material Properties
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Methods to quantify ventricle material properties noninvasively using in vivo data are of great important in clinical applications. An ultrasound echobased computational modeling approach was proposed to quantify left ...
Thermal Performance of a Radially Rotating Twin Pass Smooth Walled Parallelogram Channel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental study was performed to measure the detailed heat transfer distributions, Fanning friction factors (f), and thermal performance factors (TPF) of a radially rotating twinpass parallelogram channel. Laboratory ...
Thermal Effect on Microchannel Electro osmotic Flow With Consideration of Thermodiffusion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Electroosmotic flow (EOF) is widely used in microfluidic systems. Here, we report an analysis of the thermal effect on EOF under an imposed temperature difference. Our model not only considers the temperaturedependent ...
An Artificial Intelligence Application for In-Process Springback Control of Sheet Metal Bending
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bending is the fastest and most efficient process commonly used in the industry for processing thin metal sheets into three-dimensional shapes by localized deformation using only a single geometrical die. However, suppliers ...
Effects of Residual Stress, Axial Stretch, and Circumferential Shrinkage on Coronary Plaque Stress and Strain Calculations: A Modeling Study Using IVUS-Based Near-Idealized Geometries
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Accurate stress and strain calculations are important for plaque progression and vulnerability assessment. Models based on in vivo data often need to form geometries with zero-stress/strain conditions. The goal of this ...
Combining IVUS and Optical Coherence Tomography for More Accurate Coronary Cap Thickness Quantification and Stress/Strain Calculations: A Patient-Specific Three-Dimensional Fluid-Structure Interaction Modeling Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Accurate cap thickness and stress/strain quantifications are of fundamental importance for vulnerable plaque research. Virtual histology intravascular ultrasound (VH-IVUS) sets cap thickness to zero when cap is under ...
Optical Coherence Tomography-Based Patient-Specific Residual Multi-Thrombus Coronary Plaque Models With Fluid–Structure Interaction for Better Treatment Decisions: A Biomechanical Modeling Case Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Intracoronary thrombus from plaque erosion could cause fatal acute coronary syndrome (ACS). A conservative antithrombotic therapy has been proposed to treat ACS patients in lieu of stenting. It is speculated that the ...
