RISBrief Review of Recent Achievements in the Flamelet Manifold Selection and Probability Density Distribution for Flamelet Manifold Variables
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The flamelet model is a commonly used tool for turbulent combustion simulations in the engineering field due to its computational efficiency and compatibility with complex chemical reaction mechanisms. Despite being widely ...
The Impact of Spatial Variability of Land-Surface Characteristics on Land-Surface Heat Fluxes
Publisher: American Meteorological Society
Abstract: The impact of subgrid-scale variability of land characteristics on land-surface energy fluxes simulated in atmospheric models (e.g., GCMs) was investigated with Patchy Land-Atmosphere Interactive Dynamics (PLAID), a ...
The Beta Drift of Three-Dimensional Vortices: A Numerical Study
Publisher: American Meteorological Society
Abstract: The beta effect on translation of cyclonic and anticyclonic vortices with height-dependent circulation (the beta-drift problem) is investigated via numerical experiments using a dry version of a multilevel primitive equation ...
Velocity-to-Be-Gained Deorbit Guidance Law Using State Space Perturbation Method
Publisher: American Society of Civil Engineers
Abstract: Deorbit guidance laws steer a reentry spacecraft from the parking orbit to the entry interface (EI) while satisfying some terminal constraints. The guidance precision has great influence on the shape of the reentry trajectory, ...
An Examination of Some ENSO Mechanisms Using Interannual Sea Level at the Eastern and Western Equatorial Boundaries and the Zonally Averaged Equatorial Wind
Publisher: American Meteorological Society
Abstract: Theory suggests that the interannual equatorial Kelvin wave sea level (?W) in the western Pacific should be directly proportional to the interannual western Australian sea level, and the interannual equatorial Kelvin wave ...
On the Timing of Warm and Cold El Niño-Southern Oscillation Events
Publisher: American Meteorological Society
Abstract: Using wind and atmospheric pressure observations, the authors find that the ENSO signal has a previously unnoticed structure fundamental to ENSO dynamics and prediction. Specifically, the time ?t from the maximum of a warm ...
Calculation of Equivalent Thermal Conductivity of Motor Winding Based on Conductor Distribution
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To improve the calculation accuracy of motor thermal field, this paper proposes a method for calculating the equivalent thermal conductivity of winding based on conductor distribution, and a 24-slot 26-pole outer-rotor ...
Top-Down Hierarchical Construction and Application of a Domain Knowledge Graph Based on Multimodal Design Information
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Market demands for diversified and personalized customer needs drive the need for continuous high-speed iteration of products. Among them, product conceptual design is the core process for meeting consumer needs and ...
Experimental Research on the Impact of Driving Time on Commercial Driver’s Driving Ability
Publisher: American Society of Civil Engineers
Abstract: An investigation focusing on fatigue driving in road safety was performed using the methodologies of human factors and experimental psychology. Commercial drivers of highway passenger transport were chosen as the study ...
Numerical Investigation of the Clocking Effect Between Inducer and Impeller on Pressure Pulsations in a Liquid Rocket Engine Oxygen Turbopump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The clocking positions between the inducer and the impeller have a certain impact on the performance of the high-speed centrifugal pump, which however, is often ignored by designers. In the present study, three-dimensional ...
