Heating of non-Newtonian falling liquid film on a horizontal tube

摘要: The problem of heat transfer to non-Newtonian laminar falling liquid films on horizontal tubes is investigated theoretically for constant flux and isothermal conditions imposed at the inner periphery tube. local average coefficients are obtained as function system parameters by conjugating convective transport film thermal conduction in material tube peripheral direction. results indicate that coefficient can be described successfully three dimensionless groups characterizing dynamic flow characteristics film, modified Prandtl number index power law variation rate angular shear deformation fluid with respect stress.
