MULTIPHASE FLOW
DEF:- Interacting flow of two or more phases, where the interface between the phases is influenced by their motion.examples being gas-liquid flows in evaporators and condensers, gas-liquid-solid flows in chemical reactors, solid-gas flows in pneumatic conveying, etc
Two general topologies of multiphase flow can be usefully identified at the outset, namely disperse flows and separated flows.
Disperse flows : those consisting of finite particles, drops or bubbles (the disperse phase) distributed in a connected volume of the continuous phase. Separated flows consist of two or more continuous streams of different fluids separated by interfaces.
Multiphase modeling
There are three ways in which such models are explored:
(1) experimentally, through laboratory-sized models equipped with appropriate Instrumentation.
(2) Theoretically, using mathematical equations and models for the flow.
(3) computationally, using the power and size of modern computers to address the complexity of the flow.
From a practical engineering point of view one of the major design difficulties in dealing with multiphase flow is that the mass, momentum, and energy transfer rates and processes can be quite sensitive to the geometric distribution or topology of the components within the flow. For example, the geometry may strongly effect the interfacial area available for mass, momentum or energy exchange between the phases. Moreover, the flow within each phase or component will clearly depend on that geometric distribution.
Therefore a detail study of flow patterns is required.
Types of flow pattern(vertiacal flow)
Of the four type of Two-Phase Flow (Gas-Liquid, Gas-Solid, Liquid-Liquid and Liquid-Solid), gas-liquid flows are the
