RISDetermination of Turbulent Prandtl Number for Thermal Fluid Dynamics Simulation of HVAC Unit by Data Assimilation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Regarding high-precision temperature field prediction of a heating ventilation and air conditioning (HVAC) unit using thermal fluid dynamics simulation, the determination of the turbulent Prandtl number (Prt) was a key ...
Static–Dynamic Coupling Optimization Design of Battery Enclosure under Multigradient Loading Based on aHigh-Fidelity Digital Twin Model
Publisher: American Society of Civil Engineers
Abstract: AbstractAlthough digital twin high-fidelity models have demonstrated accuracy and effectiveness
in battery system condition monitoring, performance prediction, and other fields,
they have not yet been deeply integrated ...
Spectral Clustering and Multicriteria Decision for Design of District Metered Areas
Publisher: American Society of Civil Engineers
Abstract: The design of district metered areas (DMAs) has many factors to be considered to reduce the adverse effect of the closure of valves. A three-step methodology for DMA design is proposed based on spectral clustering algorithm ...
Iterative Methodology of Pressure-Dependent Demand Based on EPANET for Pressure-Deficient Water Distribution Analysis
Publisher: American Society of Civil Engineers
Abstract: Traditional water distribution simulations, known as demand-driven analysis (DDA), are normally analyzed under the assumption that nodal demands are known and satisfied. The DDA is valid under normal conditions and in ...
Assessment and Interpretation of the Random Field Parameters for Spatially Variable Soil Using Ball and Cone Penetrometers
Publisher: American Society of Civil Engineers
Abstract: AbstractNatural soils inherently exhibit spatial variability, which is crucial for the reliability
of foundations. However, due to spatial averaging and weakest path effects, interpreting
random field parameters of soil ...
Study on Cyclic Loading Characteristics of EH500 High-Strength Steel for Heavy Icebreakers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Heavy icebreakers are specifically designed to operate continuously in polar regions. During navigation, the hull structure withstands repeated loading and unloading effects caused by continuous collisions with ...
Free Vibration of a Fluid Loaded Ring Stiffened Conical Shell With Variable Thickness
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An analytical method is presented for the free vibration of a fluid loaded (submerged) ringstiffened conical shell with variable thickness in the low frequency range. Based on the Flأ¼gge theory and equivalent method of ...
Stationary Response Probability Distribution of SDOF Nonlinear Stochastic Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: There has been no significant progress in developing new techniques for obtaining exact stationary probability density functions (PDFs) of nonlinear stochastic systems since the development of the method of generalized ...
Model-Based Coarse-Fine Virtual Calibration and Visual Servo for Augmented Reality-Assisted Peg-in-Hole Microassembly
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A three-dimensional (3D)-virtual calibration and visual servo are implemented for augmented reality (AR)-assisted peg-in-hole microassembly operations. By employing 3D model and ray casting, the 3D coordinates on virtual ...
Keying Process of the OmniMax Anchor Shallowly Embedded in Undrained Normally Consolidated Clay
Publisher: American Society of Civil Engineers
Abstract: The OmniMax anchor is an efficient anchoring foundation due to its dynamic installation and diving property. When subjected to pullout loading, the anchor is keyed to a new orientation and position to provide holding ...
