Scaling of two-phase capillary pressure-saturation relationships: water-air and oil-air systems
immiscible phases capillary pressure-satura- tion relationship interfacial tension scaling
2008/12/2
Solutions of various problems related to soil contamination by nonaqueous phase liquids (NAPL) require a knowledge of capillary pressure-saturation relationships. In soil-water-air systems, this rela...
Air cleaning in livestock buildings by applying the granular filtration layer
ammonia emission emission reduction granular filter
2008/11/26
The assumptions and results of laboratory research on efficiency of ammonia removal from air by use of the cassette filter in the mechanical ventilation system were presented. A filtration layer consi...
Influence of vehicular traffic on air permeability and groundnut productionin a semi-arid sandy loam soil
semi-arid tillage vehicular traffic compaction
2008/11/18
The effect of vehicular traffic on the production of
groundnut (Arachis hypogea) was investigated in a sandy loam
soil. A randomized complete block design with treatments of 0, 5,
10, 15 and 20 pas...
This paper presents the results of the investigations of water-air relations in peat, sand and their mixture. It was stated that the addition of sand into peat radically changes its water...
Wind-caused air transport through greenhouse screens: a physical modelling approach
air exchange porous screen greenhouse wind pressure physical model
2008/11/10
An understanding of the air exchange through screens is needed to optimise climate control strategies in greenhouses. An analysis of the airflow through porous screens due to wind pressure was perform...
Grain drying method by using changeable air flow
Grain air discharge drying dynamics of moisture absorption
2010/1/15
The article describes a new energy saving method for drying grain. The idea of the method is that once moisture released from grain decreases, air discharge going through the grain is reduced as well....
