BT-43 Liquid Film Breakdown in Tubeside Falling Film Evaporators
May 19, 2021This report provides an overview of several mechanisms for the breakdown of falling film. Available literature and HTRI data enable confirmation of the minimum wetting flow rate calculation used in Xist 8.2 and the development of two correlations for determining Reynolds numbers for the Marangoni breakdown, one for the subcooled zone...
Research Update: 2020 - Year in HTRI Research
February 09, 2021After summarizing the results from HTRI Research over the past year, this webinar provides insights into how these results improve our technology and its use by HTRI members. Topics include prediction of hot air recirculation for air coolers, development of new non-Newtonian heat transfer correlations, modification of tubeside falling film heat...
BT-42 Improved heat transfer methods for tubeside falling film evaporators
November 17, 2020HTRI collected falling film evaporation data for two pure components and three mixtures in a vertical tube. Current falling film methods in Xist® 8.2 underpredict most of the measured heat transfer coefficients. Based on the latest data, we have improved our heat transfer methods, including a vapor-shear enhancement factor, a new mixture correction factor...
