Eucalyptus gasification using a multi-stage air gasifier: An experimental study [PDF]

open access: yesBIO Web of Conferences
Eucalyptus is a fast-growing plant with high energy, so it is potential as a renewable energy source. Eucalyptus can be converted into synthesic gas containing CO and H2 for direct fuel or raw chemical production materials with gasification techniques ...

A Simplified Higher Order Closure + Mass Flux Boundary‐Layer Parameterization in the Goddard Earth Observing System

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.
Abstract Boundary‐layer turbulence and clouds play an essential role in regulating surface fluxes and the Earth's radiative balance, but their parameterization in global models remains a significant source of uncertainty. This paper describes a novel implementation of the Simplified Higher Order Closure (SHOC) coupled with a multi‐plume eddy ...

The LASSO‐CACTI Library of Deep Convection Simulations for Córdoba, Argentina: Overview of Mesoscale and Large‐Eddy Simulations

open access: yesEarth and Space Science, Volume 13, Issue 9, September 2026.
Abstract The U.S. Department of Energy Atmospheric Radiation Measurement (ARM) User Facility recently released ensembles of high‐resolution atmospheric simulations of deep convection to complement ARM's measurements. These simulations are from the Large‐Eddy Simulation (LES) ARM Symbiotic Simulation and Observation (LASSO) activity and are for 20 case ...

Gasification of Apricot Pit Shells in a Downdraft Gasifier

open access: yes, 2009
In this study, gasification potential of apricot pit shells is investigated by a pilot scale downdraft gasifier. Apricot shells could be gasified in a downdraft gasifier to produce clean gas with a calorific value of around 5.82 MJ/Nm3 and with a ...

A numerical study of convective-scale downdrafts in the outer core of tropical cyclones in vertically varying environmental flows

open access: yesTropical Cyclone Research and Review, 2020
The characteristics of convective-scale downdrafts in the outer core of tropical cyclones in the lower- and upper-layer vertical wind shear (VWS) are investigated based on two high-resolution idealized numerical experiments.

Sea Surface Temperature Feedbacks and Convective Organization Mediate the Tropical Circulation Response to Aerosols

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Coupling between aerosols, atmospheric circulation, and tropical sea surface temperature (SST) patterns is an important part of anthropogenic influence on climate but is not well understood. Using idealized, cloud‐resolving simulations with a slab ocean, we examine the hydrologic and circulation responses to uniform and spatially varying ...

Energy Efficient Measures to Avoid Downdraft from Large Glazed Facades [PDF]

open access: yes, 1995
Glazed facades may cause thermal discomfort due to downdraft. Convectors placed close to the facade can prevent downdraft but can cause an increase in the energy consumption. The objective of this research was to investigate whether the structural system
