Autor: Salvatore Straface, Lorenzo Pugliese, Tjalfe G. Poulsen, Eriona Canga
Publikováno v: Pugliese, L, Poulsen, T G, Canga, E & Straface, S 2020, ' Linking mean pore velocity and dispersivity to pore velocity distribution by advection–dispersion and stream tube modeling ', Environmental Fluid Mechanics, vol. 20, no. 6, pp. 1617-1636 . https://doi.org/10.1007/s10652-020-09757-3
A large set of experimental solute tracer breakthrough data (corresponding to more than 350 individual tracer breakthrough curves) in eight granular filter materials, were used to investigate the links between solute dispersivity and the shape of the

Water evaporation from cracked soil under moist conditions as related to crack properties and near-surface wind speed
Autor: Tjalfe G. Poulsen, Ankit Garg, Weiling Cai
Publikováno v: European Journal of Soil Science. 71:627-640
The impacts of five factors (wind speed, crack width, crack distance, crack depth and crack orientation (compared to wind direction)), on evaporation from cracked soil under moist soil conditions were investigated experimentally. Experiments were car

Influence of biochar addition on gas permeability in unsaturated soil
Autor: Sanandam Bordoloi, Junjun Ni, Peng Lin, Guoxiong Mei, Tjalfe G. Poulsen, P. G. Maddibiona, Ankit Garg, Weiling Cai
Publikováno v: Géotechnique Letters. 9:66-71
Biochar (BC) has been proposed as an alternative soil amendment in landfill cover. Its effects on soil hydraulic properties (e.g. soil water retention) have been explored to some extent, while its influence on landfill gas flow characteristics is not

Predicting below-surface pore velocity profiles in porous media from above-surface wind speed and porous medium gas permeability
Autor: Tjalfe G. Poulsen
Below-surface horizontal pore air velocity profiles in porous media in response to above-surface wind conditions were measured for 16 combinations of wind speed (1.4 – 5.7 ms-1) and main wind gust frequency (0 – 1 Hz) in four granular porous medi

Improvement in CH 4 /CO 2 ratio and CH 4 yield as related to biomass mix composition during anaerobic co-digestion
Autor: Mona Wells, Tjalfe G. Poulsen, Laetitia Adelard
Publikováno v: Waste Management
Waste Management, Elsevier, 2016, ⟨10.1016/j.wasman.2016.11.009⟩
Sixteen data sets (two of which were measured in this study) with a combined total of 145 measurements of ultimate methane yield (UMY) during mono- and co-digestion of ternary biomass mixtures were used to assess impact of co-digestion on the relativ
