One of the primary factors for generating heating and cooling loads in apartment houses is infiltration. However, evaluation method infiltration rates has not been well established Korea. The existing measures air change per hour a house at 50 Pa (ACH50) divides it by leakage–infiltration ratio, N = 20, as suggested Lawrence Berkeley National Laboratory (LBL). In this study, to evaluate average...

Abstract Rain gardens have been recognized as an effective device for on-site runoff volume reduction and storm water quality enhancement. A rain garden is designed as an infiltration basin with a shallow, wide water storage volume. The sub-base underneath the basin bottom is structured as a two-layered filtering medium. The upper sand layer provides the required filtering process and then the ...

Fluid flow through minerals pores occurs in underground aquifers, oil and shale gas reservoirs. In this work, we explore water and oil flow through silica nanopores. Our objective is to model the displacement of water and oil through a nanopore to mimic the fluid infiltration on geological nanoporous media and the displacement of oil with and without previous contact with water by water floodin...

The variation in moisture content between subsequent irrigations determines the use of infiltration equations that contain representative physical parameters soil when irrigation begins. This study analyzes reliability hydrodynamic model to simulate advanced phase border irrigation. For solution model, a Lagrangian scheme implicit finite differences is used, while for infiltration, Kostiakov eq...

infiltration in furrow irrigation is 2-d which depends on both time and surface characteristics at which infiltration occurs. however, in many furrow irrigation models, infiltration is determined as a function of infiltration time opportunity, assuming the variation of weted perimeter is low along furrow. in order to compare the proposed asumptions, two zero-inertia furrow irrigation models wer...

BACKGROUND Hodgkin's disease is a malignant process of lymphoreticular system that constitutes 6% of childhood cancers Accurate staging of lymphoma is the basis for rational therapeutic planning and assessment of the presence or absence of marrow involvement is a basic part of the staging evaluation. The objective of this study was to determine the incidence of marrow infiltration in paediatric...
