Study and analysis of the energy consumption of a Lidl shop

The assignment is part of Lidl's initiative to limit the environmental impact of its shops. Four students therefore formed a focus group tasked with analysing the energy consumption of the shops. Using one of the sites, they identified the most relevant energy consumption items and benchmarked the technical solutions that would enable effectively reducing this consumption. This work enabled them to formulate recommendations that could be used directly by Lidl.

Duration: 3 months

SIDEM VEOLIA

Analysis and research into the causes of nozzle vibration fatigue

The study focuses on the nozzle of an ejector at a desalination site operated by SIDEM, which has suffered repeated damages. In collaboration with CEMEF (Center for Material Forming of the École des Mines de Paris), two studies were conducted simultaneously: one on structural mechanics and the other on fluid mechanics. An iterative approach, involving various simulations, allowed the determination of the resonance frequencies of the system and the fluid-induced excitation frequencies. These results enabled the proposal of improvement strategies for the ejector to prevent further damages caused by system vibrations.

Duration: 2 months

Fluid mechanics

Feasibility study of air purification in a confined space

The study looks at the air quality in a metro station. Using 3D modelling, the aim is to optimise the location of clean air supply and stale air extraction nozzles to maintain air quality in the structure independently of mechanical ventilation. Simulations were carried out in collaboration with CEMEF (Centre de Mise en Forme des Matériaux de l'École des Mines de Paris) to determine the optimum configuration for the nozzles.
