چکیده

This paper is about the analysis 0f the liquid discharge by falling film within a distillation tube. Specifically about some flow rates that can be used in this process, when we talk about film ́s discharge and maintenance. This aim of this paper is to study through simulations in CFD (Computational Fluid Dynamics) what influence the feeding flow rate has on the film ́s formation, its stability and thickness. This distillation process has low resistance to the liquid flow and high capability of separation, besides a simple construction unity. The commercial code used in order to solve the mathematical modeling was ANSYSY CFX 12.0. The results obtained show that the best results achieved were low feeding flow rates, which provided a rather stable and continuous film and lower values of vapor superficial velocity.

Hydrodynamics of Sieve Tray Distillation Column Using CFD Simulation

Sieve trays are widely used in the gas- liquid contactors such as distillation and absorption towers. In this article, a three-dimensional, two phase CFD model using Euler-Euler framework was developed to simulate a distillation tower with two sieve trays. Hydrodynamic simulation of air and water system in different rates of gas phase was carried out and velocity distribution parameters, clear ...

Improving Heat Transfer in Falling Film Evaporators in Food Industries

Falling film evaporators, due to their high heat transfer coefficients, low energy loss, rather a low holdup time, and the ability to handle high capacities have broad applications in food industries. Thus, this kind of evaporator is being used in the production of temperature sensitive compounds such as syrups. In this study, through modelling of the falling film evaporator with the use of...

CFD Modeling of the Feed Distribution System of a Gas-Solid Reactor

Granular flow simulation using CFD has received a lot of attention in recent years. In such cases, CFD is either, coupled with Discrete Element Method (DEM) techniques for appropriate incorporation of inter-particle collisions, or the Eulerian CFD approach is used in which granular particles are treated as they were fluid. In the present study, a CFD analysis was performed...

CFD Simulation of Concap Tray Hydrodynamics

This research includes both experimental and CFD investigation in the hydrodynamic behavior of a new type of column tray introduced as “Concap” tray. The proposed column tray is used in contactor columns especially in stripping columns. The hydrodynamics of this Concap tray is investigated in a 1.2m in diameter column. Using air-water system, the experiments were performed for different liquid ...
