Abstract

The liquid-gas interfacial configurations in angular pores of plant growth media under microgravity were investigated. The Augmented Young-Laplace equation was employed to simultaneously consider contributions of capillary and adsorptive forces to interfacial configurations. It was observed that the difference between gravity conditions for liquid held between parallel plates became significant only for pores larger than approximately 1 mm and potentials very close to zero. Implications of liquid configurations on gas entrapment processes and on macroscopic retention and transport properties relevant to root module design were also discussed.
