摘要: Bubble phase hold-up is one of the most important parameters characterizing bubble column hydrodynamics because it not only gives volume fraction gas but also required to estimate interfacial area and thus mass transfer rate between liquid phases. characterized by different flow patterns depending on several such as rate, design, fluid properties. Heterogeneous distribution within that induce density fluctuations originate circulation patterns, strongly influencing mixing parameters. In this chapter, profiles their measurements are discussed. The various models analyze explained. effects variables in inverse
