A two-dimensional trickle film flow model consisting of a vertical column of horizontal rods is used to provide the liquid-solid mass transfer characteristics of a gas-continuous and fully wetted film flow trickle bed reactor. Local and average liquid-solid mass transfer rates are determined with the limiting current technique. Local Sherwood number variation with angular position is measured for 400 < Re < 2000. With a unique method of manipulating electrochemical mass transfer measurements, the existence of two vortices behind a flow separation is revealed. © 1987.
