A Combination Of Computational Fluid Dynamics (Cfd) And Adaptive Neuro-Fuzzy System (Anfis) For Prediction Of The Bubble Column Hydrodynamics

Faculty of Engineering University of Malaya

This paper shows a combination of computational fluid dynamics (CFD) and adaptive neuro-fuzzy inference system (ANFIS) to propose a new viewpoint for multiphase flow modeling, including the accuracy of soft computing techniques in the prediction of a three dimensional (3D) bubble column reactor. Since there are some difficulties (i.e., high computational time in numerical methods and expensive equipment in experimental techniques) in predicting bubble column reactors, particularly at different column locations and various operation conditions, soft computing methods can be developed as a favorable replacement for conventional measurement and prediction techniques. This study employs CFD beside the ANFIS method to …

Performance Evaluation Of Natural Ventilation Devices To Improve Thermal Comfort Of A Computer Lab Of University Building Using Cfd As A Tool, Innovative Research Publications Irp India, Dipesh Kumar, Abhishek Jatav

Innovative Research Publications IRP India

Air circulation study is most important part for any building; so that engineers can optimize thermal comfort for buildings. A computer lab located in university building of Jaipur city is used in this study. Main aim of this study is to optimize computer lab for two types of conditions, first is only internal fans are in operational condition and second condition is effect of room window opening and closing. Thermal comfort parameters are used for analysis. Model equations are also generated in this steady using advanced D.O.E. (design of experiment) technique. Computational fluid dynamic (CFD) studies were carried out by …

Modelling Three-Phase Flow In Metallurgical Processes, Christoph Goniva, Gijsbert Wierink, Kari Heiskanen, Stefan Pirker, Christoph Kloss

Gijsbert Wierink

The interaction between gasses, liquids, and solids plays a critical role in many processes, such as coating, granulation and the blast furnace process. In this paper we present a comprehensive numerical model for three phase flow including droplets, particles and gas. By means of a coupled Computational Fluid Dynamics (CFD) - Discrete Element Method (DEM) approach the physical core phenomena are pictured at a detailed level. Sub-models for droplet deformation, breakup and coalescence as well as droplet-particle and wet particle-particle interaction are applied. The feasibility of this model approach is demonstrated by its application to a rotating drum coater. The …

Numerical Simulation Of The Filling And Curing Stages In Reaction Injection Moulding, Using Ansys Cfx, Rui Igreja

Rui Igreja

Commonly used methods for injection moulding simulation involve a considerable number of simplifications, leading to a significant reduction of the computational effort but, in some cases also to limitations. In this work, Reaction Injection Moulding (RIM) simulations are performed with a minimum of simplifications, by using the general purpose CFD software package Ansys CFX, designed for numerical simulation of fluid flow and heat and mass transfer. The Ansys CFX’s homogeneous multiphase flow model, which is generally considered to be the appropriate choice for modelling free surface flows where the phases are completely stratified and the interface is well defined, is …
