Due to complexity of condensate-migration into a porous-bed, the analytically simplified studies using uniform-flow assumption need enhancement through performing experiments. This study is conducted by maintaining saturated vapor-air over porous-alumina-balls and glass-beads-bed in a nonperforated chamber. Walls of the chamber are controlled isothermally. By evaluating on subcooling-, diffusive-, and porous perturbation-parameter, it is known that condensate migrates in Darcian regime. In this regime, based on visualized evidence and proposed Lyapunov-exponent-base series, this migration study finds that there are periodic- and unperiodic-dominant subregimes, where a temporal chaotic-migration case is found in the unperiodic-dominant subregime.
