RISTime-Resolved Measurement of Droplet Size and Concentration in Cloud Chambers
Publisher: American Meteorological Society
Abstract: An optical method for measuring droplet size and concentration in a cloud chamber on a time-resolved basis is discussed. During the growth of the droplets, speed transmission at two wavelengths of light is continuously ...
The Monte Carlo Independent Column Approximation’s Conditional Random Noise: Impact on Simulated Climate
Publisher: American Meteorological Society
Abstract: The Monte Carlo Independent Column Approximation (McICA) method for computing domain-average radiative fluxes is unbiased with respect to the full ICA, but its flux estimates contain conditional random noise. Results for ...
Validation of Analytical Model for Turboelectric Power System for Preliminary Design Purposes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Small, electrically powered, unmanned aircraft are limited in the range and endurance due to inherently low energy density of batteries, prompting the development of hybrid gaselectric power systems. Turbo-electric power ...
Comparisons of Horizontal Axis Wind Turbine Wake Interaction Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, Reynoldsaveraged Navier–Stokes (RANS) simulations are performed using the kخµ and kد‰ shear stress transport (SST) turbulence closure schemes to investigate the interactions of horizontalaxis wind turbine ...

Pilot-Scale Investigation of Passive Methane Oxidation System Materials Performance under Seasonal Temperature Variations
Publisher: American Society of Civil Engineers
Abstract: Passive methane oxidation systems (PMOSs) including biocovers and biowindows are innovative solutions to mitigate methane (CH4) emissions from landfills. In this study, the performance of different methane oxidation layer ...
Representing El Niño in Coupled Ocean–Atmosphere GCMs: The Dominant Role of the Atmospheric Component
Publisher: American Meteorological Society
Abstract: A systematic modular approach to investigate the respective roles of the ocean and atmosphere in setting El Niño characteristics in coupled general circulation models is presented. Several state-of-the-art coupled models ...
Performance of Biocover Materials in Mitigating Methane Emissions from Landfills under Different Loading Rates
Publisher: American Society of Civil Engineers
Abstract: Biocovers are an innovative solution to reduce methane (CH4) emissions from landfills. This study investigates the performance of biocover materials, including food waste compost, yard waste compost, and peat moss, in ...
