CFD modeling and simulation of indoor air pollution

Abstract

Indoor air quality is becoming a major topic of interest nowadays due to the fact that humans spend most of their time at the interiors of buildings’ envelopes. Thus, reducing pollutants in air by adsorptive materials/surfaces is an interesting topic for research and development. The major objective is to characterize and quantify the potential of adsorptive materials in reducing air pollution and thus improving the indoor overall air quality (i.e. as air purifier tools). Rare numerical techniques have been developed in the literature for the modeling and simulation of air pollution using CFD tools [1-4]. Due to the complexity of the physical phenomena involved, the existing CFD techniques are dispersed in the litterature introducing many simplications into the modeling of the real physical phenomena behind adsorption.

In this Masters research, first, it is required to conduct an intense bibliography study in order to identify the potential of CFD tools in reducing the indoor air pollution by applying adsorptive materials/walls.
Second, in this purpose, a CFD methodology/protocol will be developed and adopted (i.e. models choice and initial and boundary conditions strategy). Then, the successful candidate may implement some new models (in OpenFOAM® or Star-CCM+®) and then conduct CFD simulations on an air purifier case (i.e. a test case in 3D (to be defined) for predicting indoor air pollution evolution in a room in the presence of adsorptive materials/walls).

At the end, a detailed scientific report of the developed methodology and the CFD results will be analysed, discussed and presented.

Institution host :
IMT Lille Douai represents the largest engineering school in the north of Paris graduating future engineers and scientific experts. In a partnership with the University of Lille, each year the IMT Lille Douai, an engineering school of the IMT (Institut Mines-Télécom), graduates more than 500 talented engineers, trained to overcome the engineering, economic and social challenges.
This Masters research proposal will be hosted by the Energy Engineering Department (DEI) of IMT Lille Douai situated in the research center in Douai city (around 40 km to Lille). The successful candidate will work, for about 4 to 5 months, on a research topic entitled « CFD modeling and simulation of indoor air pollution in a room with adsorptive walls/materials ». This Masters research topic will be co-supervised by two researchers from DEI of Douai (Dr. Talib DBOUK and Dr. Rémi GAUTIER) and by three researchers from the technical university of Wien in Austria (Prof. Michael HARASEK, Dr. Bahram HADDADI and Dr. Christian JORDAN).

Information :
The successful candidate will benefit from a net salary around 450 euros per month during the Masters research 4 to 5 months period in Douai city. The starting date can be anytime between the 1st of Mars and the 3rd of April 2018.

The successful candidate should have good physical and numerical backgrounds in chemical engineering science and adsoprtion phenomena with good experience in numerical Fluid Dynamics, and CFD simulation tools/techniques. She/He should have a good appetite for some numerical developments. Good knowledge of C++ and java (or python) and the use of OpenFOAM® and/or Star-CCM+® will be very appreciated. The candidate should be highly motivated for research, and keen to work as part of a team and in a multidisciplinary environment.
