Origin: [Cf. F. imbibition.]
Imbibition is defined as the displacement of one fluid by another immiscible fluid. This process is controlled and affected by a variety of factors. In spontaneous imbibition of wetting liquids into porous media, the capillary pressure, created as a result of interplay of the liquid and solid surface energies, is responsible for the spontaneous suction of the liquids. The capillary number and the mobility ratio have the greatest importance. It is also defined as the phenomenon by which the living or dead plant cell absorbs water by surface attraction. A classification of imbibition processes was given by Payatakes and Dias: In a two-phase flow in porous media, imbibition is one of the two types of displacement, the other one being drainage. Imbibition occurs when a wetting fluid displaces a non-wetting fluid, contrary to drainage where a non-wetting phase displaces the wetting fluid. The two processes are governed by different mechanisms and should not be confused. ⁕Spontaneous imbibition ⁕Constant influx ⁕Quasi-static imbibition ⁕Dynamic invasion with constant flow rate of the displacing fluid One example of imbibition that is found in nature is the absorption of water by hydrophilic colloids. Matrix potential contributes significantly to water in such substances. Examples of plant material which exhibit imbibition are dry seeds before germination. Imbibition can also entrain the genetic clock that controls circadian rhythms in Arabidopsis thaliana and other plants. Another example is that of imbibition in the Amott test.
