The coarse-grained brownish yellow wood of a small tree (Pisonia obtusata) of Florida and the West Indies
Geologically, this term describes rock that permits movement of fluids through small, often microscopic openings, much as water moving through a sponge Porous rocks may contain gas, oil, or water
Of or pertaining to pornography; lascivious; licentious; as, pornographic writing
able to absorb fluids; "the partly porous walls of our digestive system"; "compacting the soil to make it less porous"
full of pores or vessels or holes able to absorb fluids; "the partly porous walls of our digestive system"; "compacting the soil to make it less porous"
Something that is porous has many small holes in it, which water and air can pass through. The local limestone is very porous
containing pores, or holes that permit the movement of fluids or gases An example of a porous material is a sponge Porosity is the extent to which a substance contains pores Swiss cheese has high porosity compared to cheddar
Full of pores; having interstices in the skin or in the substance of the body; having spiracles or passages for fluids; permeable by liquids; as, a porous skin; porous wood
A porous medium or a porous material is a solid (often called frame or matrix) permeated by an interconnected network of pores (voids) filled with a fluid (liquid or gas). Usually both the solid matrix and the pore network (also known as the pore space) are assumed to be continuous, so as to form two interpenetrating continua such as in a sponge. Many natural substances such as rocks, soils, biological tissues (e.g. bones), and man made materials such as cements, foams and ceramics can be considered as porous media. A poroelastic medium is characterised by its porosity, permeability as well as the properties of its constituents (solid matrix and fluid)
A solid that contains pores; normally, it refers to interconnected pores that can transmit the flow of fluids (The term refers to the reservoir geology when discussing GEOTHERMAL sites)
