Experimental and Analytical Study on Pool Scrubbing Under JET Injection Regime

Monte Carlo simulation of aerosol transport in rising gas bubbles undergoing shape deformation

“…For parametric calculations the particle properties were chosen to be similar to the bulk of the particles used in the experiments of Herranz et al (1997), to be described later. The particles were thus assumed to be spherical, made of Nickel, and have diameters in the 0.25-2.5 m range.…”

“…These rising bubbles remain stable (i.e., do not break up) while undergoing shape change. Furthermore, as will be discussed later, the selected sizes are good representations of the experiments of Herranz et al (1997). Figs.…”

“…An experimental study of pool scrubbing of simulated radioactive aerosols was performed by Herranz et al (1997). In these experiments, the aerosol was injected through a horizontal submerged vent, and subsequently formed a rising bubble plume in a pool.…”

“…Transport of particles in bubbles is common in wet scrubbing processes, and in the phenomenology of certain accident scenarios for boiling water reactors (BWRs) and liquid metal fast breeder reactors (LMFBRs), (Owczarski, Postma, & Schreck, 1985;Wassel, Mills, & Bugby, 1985;Jonas & Schültz, 1988;Ghiaasiaan, Wassel, & Lin, 1993;Calvo, Guntay, & Ramsdale, 1991;Miyahara & Sagawa, 1996;and Herranz et al, 1997). Rigorous modeling of particle removal in rising bubbles is difficult, however, due to the complicated bubble hydrodynamics and the coupling among a multitude of mechanisms that contribute to particle motion.…”

In the latter applications, important aerosol transport phenomena occur in a number of processes, including during the time the bubble is rising in the pool.…”
