ABSTRACT Remote sensing techniques have been used to study and track wildfire smoke plume structure evolution; however, knowledge gaps remain because of the limited availability observational datasets aimed at understanding fine-scale fire–atmosphere interactions microphysics. Meteorological radars investigate evolution rise in time space, but highly resolved observations are limited. In this s...

A kinetic model for predicting biochar, producer gas, and tar formations of top-lit updraft (TLUD) gasification was developed. The three main zones within the TLUD gasifier, pyrolysis, incomplete combustion, reduction reaction zones, were incorporated into sequentially solved. Validated with experimental data, found capable biochar yield on pine woodchips at varying airflow rates, biomass moist...

Abstract This study investigates the sensitivities of mesoscale convective system (MCS) low-frequency gravity waves to changes in vertical wind and thermodynamic profile through idealized cloud model simulations, highlighting how internal MCS processes impact wave generation, propagation, environmental influence. Spectral analysis is performed on rates latent heat release, updraft velocity, dee...

banded ultra-violet solar radiation, the high-rise solar tower to updraft the heated air to the atmosphere, and in between the power conversion unit, where a system of coupled turbines and generators transforms the stream of heated air into electric power. A good efficiency of the power plant can only be reached with extra-large dimensions of the tower and/or the collector area. The paper prese...
