Modeling And Hydrodynamics Study Of A Thin Liquid Film Flow Over Horizontal Spinning Disk

A thin liquid film flow over horizontal spinning disk under influence of centrifugal field is one of the implementation and method in process intensification. Hydrodynamics study and development of mechanistic model is strongly desirable to describe this film flow behaviors. Thus, Navier-Stokes equa...
