Film Coefficients with Fluids Outside Tubes Forced Convection
Film coefficients for turbulent flow that exist on the outside or shell-side of the conventional baffled shell and tube exchanger are correlated for hydrocarbons, organic compounds, water, aqueous solution and gases by [5,70]:
and as represented in Figure 15-84 (S.I. units), deviation: 0 to +20%. The Gs is correlated for both cross and parallel flow through the bundle by using the hydraulic radius along the tubes only . Figure 15-85 is helpful in visualizing shell-side fluid flow.
