Condensate Migration Dynamics into Porous Bed in a Nonperforated Chamber

Abstract

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.

Convective Regimes on Porous Media within Sudden Changed Channel due to Tangential Gas Flow

“…Experiment using tangential flow velocity of gas phase or air-moist, over a porous nonconsolidated aluminum media has already been done [9], [10], and [11]. The studies have used a sudden enlarged-contracted shape chamber, however, influence of the shape toward heat transfer in the system has not been reported yet.…”
