ONE DIMENSIONAL TRANSPORT IN LAMINAR FLOW (SHELL BALANCE)
General method of shell balance approach to transfer problems; Choosing the shape of
the shell; most common boundary conditions; momentum flux and velocity distribution for
flow of Newtonian and non-Newtonian fluids in pipes, for flow of Newtonian fluids in planes,
slits and annulus. Heat flux and temperature distribution for heat sources such as electrical,
nuclear, viscous and chemical; forced and free convection; mass flux and concentration profile
for diffusion in stagnant gas, systems involving reaction and forced convection.
Objective:
Emphasizes on deriving appropriate differential balances such as momentum, thermal
energy, and mass species, accounting appropriately by convective and diffusive (molecularscale) fluxes, with sources and sinks.
