Establishment of the falling film evaporation model and correlation of the overall heat transfer coefficient [PDF]
Royal Society Open Science, 2019 In order to study the heat transfer of the falling film evaporator with phase change on both sides, in this paper we built the mathematical model and the physical model where the liquid film inside the tube is laminar and turbulent. The film thickness of

Introducing ultrasonic falling film evaporator for moderate temperature evaporation enhancement
Ultrasonics Sonochemistry, 2018 In the present study, Ultrasonic Falling Film (USFF), as a novel technique has been proposed to increase the evaporation rate of moderate temperature liquid film. It is a proper method for some applications which cannot be performed at high temperature, such as foodstuff industry, due to their sensitivity to high temperatures.

Heat Transfer Enhancement of Falling Film Evaporation on a Horizontal Tube by Thermal Spray Coating
Applied Sciences, 2020 Falling film evaporators are gaining popularity as substitutes to typical flooded evaporators because of their low refrigerant charge. It is important to form and keep a thin liquid film on the heat transfer surface to ensure their high heat transfer ...

Modelling of a falling-film evaporator for adsorption chillers
International Journal of Refrigeration, 2023 The objective of the present study was to develop a dynamic model to simulate a prototype falling-film evap-orator that is part of a single-bed adsorption chiller test bench located at the Department of Energy of the Politecnico di Milano. The model is based on the evaporator energy and mass balances and was calibrated and validated using experimental ...

Modeling of a falling film evaporator [PDF]
Linköping Electronic Conference Proceedings, 2012 Falling film evaporators have demonstrated a good performance in air-conditioning and refrigeration. This paper presents the development of a detailed falling film evaporator model. The model is based on classical Newton’s viscosity law and Nusselt falling film theory.
