Darcyjev protok nafte u proslojku dvojne propusnosti

open access: yes, 2018
Hidrauličko frakturiranje se koristi u svrhu poboljšavanja propusnosti kompaktnih slojeva kao što su šejlovi od 1947. godine, u svrhu stimuliranja proizvodnje nafte i plina. U radu su opisane dvije teorije dizajna frakture - Perkin-Kern-Nordern model (PKN model) koji pretpostavlja da je širina frakture funkcija visine i da je fraktura oblika elipse i ...

BRZINA I PROTOK ZRAČNE STRUJE KOD RAZLIČITIH TIPOVA RASPRŠIVAČA

open access: yes, 2016
The objective of this study was to determine the vertical air flow velocity considering two different air flows on the axial and radial mistblower. With axial mistblower the air flow of 10995.75 and 14154.75 m3/h is used, and with radial mistblower the air flow of 6248.33 and 10265.16 m3/h. Axial mistblower achieves greater air flow with minor velocity,

Primjena protoke zagađenja u opisivanju transporta zagađenja u vodonosivim tlima

open access: yes, 2003
Analitical sollution for solute flux in dipsersive transport in aquifers is presented in basic terms. The stochastic analysis and solute flux approach represent the efficient way to handle the spatial variability in the properties of geologic media and to reflect its effect on the prediction of the groundwater velocities and concentrations of ...

Primena modela diskretnih elemenata na protok zrnastog materijala u pužnom transporteru

open access: yes, 2016
Fifteen horizontal single-pitch screw conveyors with modified geometry and the different lengths were investigated for premixing action, during the transport of materials. All investigations were performed experimentally and numerically, by using Discrete Element Method (DEM).

Protok energije između vodenih i kopnenih ekosustava: leteća izmjena igrača

open access: yes, 2014
The circulation of energy is not confined to a single ecosystem but there is a reciprocal subsidy transfer between adjacent habitats. Peak productivities in adjacent ecosystems can alternate thus changing the direction of energy flow. The most of its energy in an oligotrofic lotic system provides from outside (allochtonus) sources.
