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

Experimental study on a spray and falling-film cooling system
Case Studies in Thermal Engineering, 2021 After spraying, the cooling medium retains potential cooling capability and, consequently, can form a falling film to further cool the downward area. In this paper, the flow patterns and the heat transfer coefficients are correlated respectively in the ...

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 ...

On the dynamics of 3D electrified falling films
Discrete and Continuous Dynamical Systems, 2021 In this article, we consider a non-local variant of the Kuramoto-Sivashinsky equation in three dimensions (2D interface). Besides showing the global wellposedness of this equation we also obtain some qualitative properties of the solutions. In particular, we prove that the solutions become analytic in the spatial variable for positive time, the ...
