Super-scaling of wind gusts with thermal downdrafts in cloud-resolving simulations

Weather and Climate Extremes
Severe convective wind gusts (≥25ms−1) can cause significant local damage, but their small-scale nature makes them difficult to predict. This study aims to understand how gusts are simulated and to investigate the factors that control their strength ...

Mathematical modelling and optimization of biomass-plastic fixed-bed downdraft co-gasification process

EPJ Web of Conferences, 2017
Co-gasification of woody biomass and polyethylene is studied using mathematical modeling. The gasification process is downdraft fixed-bed. Comparison of modeling results with some experimental data is made.

Modelling of selected waste biomass downdraft gasification [PDF]

, 2018
Gasification of waste biomass has double benefit since it presents an efficient and environmentally friendly procedure to produce energy. Modelling of gasification of demolition wood and coffee waste, and their mixtures, in downdraft gasifier is ...

Establish Feasibility for Providing Passive Cooling With Solar Updraft and Evaporative Downdraft Chimneys

, 1987
Natural draft towers can be used for cooling and ventilating structures. From an operational perspective, the downdraft evaporatively cooled tower is preferred for a dry climate. Solar chimneys, when used alone, tend to require an excessively large solar

Short-rotation eucalyptus as a biomass fuel

California Agriculture, 1980
Rapidly resprouting eucalyptus, harvested twice annually, produced fuel for downdraft gasifiers at lower cost than is possible with most annual crops. Yields were up to 22 tonnes per hectare per year.
