3 0 0 3
UNIT I CHARACTERISTICS OF MULTIPHASE FLOWS 9
Significance of multiphase flows, important non-dimensional numbers, parameters of
characterization, calculation and measurement of particle size, size distributions and
moments, size distribution models
UNIT II PARTICLE FLUID INTERACTION 9
Equation of motion for a single particle, calculation of drag, motion of a particle in twodimensions,
effects of unsteady and non-uniform flow fields, effects of acceleration,
effects of coupling; Interaction between particles – mechanisms of interaction,
interparticle forces, hard sphere model, soft sphere model, discrete element modeling,
semi-empirical methods, kinetic theory, force chains.
UNIT III MODELLING OF MULTIPHASE FLOWS 9
Flow patterns - identification and classification - flow pattern maps and transition -
momentum and energy balance - homogeneous and separated flow models -
correlations for use with homogeneous and separated flow models - void fraction and
slip ratio correlations - influence of pressure gradient - empirical treatment of two phase
flow - drift flux model - correlations for bubble, slug and annular flows
UNIT IV CONSERVATION EQUATIONS 9
Averaging procedures - time, volume, and ensemble averaging, quasi-one-dimensional
flow, two-fluid volume-averaged equations of motion, turbulence and two-way coupling.
UNIT V MULTIPHASE SYSTEMS 9
Flow regime and hydrodynamic characteristics of packed bed, fluidized bed, pneumatic
conveying, bubble column, trickle beds; Conventional and novel measurement
techniques for multiphase systems including CARPT, Laser Doppler anemometry,
Particle Image Velocimetry.
