Webeffectieve porositeit. Definitie (nl) het volume van de poriën, dat beschikbaar is voor transport van vloeistof, gedeeld door het totale volume van de grond (bodemdeeltjes en poriën). Afkorting. ne. Synoniem (nl) beschikbaar poriëngehalte. Label (en) effective … Ineffective porosity (also called closed porosity) Refers to the fraction of the total volume in which fluids or gases are present but in which fluid flow can not effectively take place and includes the closed pores. Understanding the morphology of the porosity is thus very important for … Meer weergeven Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%. Strictly speaking, … Meer weergeven Used in geology, hydrogeology, soil science, and building science, the porosity of a porous medium (such as rock or sediment) describes … Meer weergeven Casting porosity is a consequence of one or more of the following: gasification of contaminants at molten-metal temperatures; … Meer weergeven • Void ratio • Petroleum geology • Poromechanics • Bulk density • Particle density (packed density) Meer weergeven In gas-liquid two-phase flow, the void fraction is defined as the fraction of the flow-channel volume that is occupied by the gas phase or, alternatively, as the fraction of the cross-sectional area of the channel that is occupied by the gas phase. Void fraction … Meer weergeven The ratio of holes to solid that the wind "sees". Aerodynamic porosity is less than visual porosity, by an amount that depends on the constriction of holes.
