Category: FALLING FILM

The purpose of this webinar is to discuss industry experience with vertical tubeside falling film evaporators, including specified applications and design principles for configuration. In this webinar, we identify potential design problems in keeping tube walls wet and discuss HTRI’s current methods in addressing these concerns within Xist....

With p-xylene as the test fluid, HTRI collected data for both cocurrent and countercurrent flow in a vertical tubeside falling film evaporator (FFE) test section. Preliminary results for a single-component fluid indicate that HTRI methods predict heat transfer coefficients within ±35%; that pressure drop trends with the flow regime parameter; and...

HTRI Report BT-10 documents HTRI sponsored research on falling film evaporation of glycol/water solutions at Lehigh University during the period 1986 - 1988. In that document it was reported that evaporating films composed of mixtures of ethylene glycol and water break down at much lower heat fluxes for a given flow...

HTRI Report BT-10 documents HTRI sponsored research on falling film evaporation of glycol/water solutions at Lehigh University during the period 1986 - 1988. In that report the required mass transfer correction to heat transfer was determined by a mass diffusion method applying only to binary mixtures. This Research brief makes a...
