II- Description of the 3 year doctoral research project
(Please make a complete description of the doctoral research project. Do not forget to mention
when the contract will start and to give an estimation of the net salary per month)
II.1. Research project:
The main objectives of this research project are:
- to develop an innovative electrostatic cleaning system to remove fine particles from solar panels,
- and to study the three-dimensional movements of particles induced by a non-uniform electric field.
Description
In the ElectroFluidoDyanmic (EFD) team at Pprime Institute, intense electric fields are widely used
to control the trajectories of charged particles in many applications, such as the electrostatic
precipitation of ultrafine particles (size < 1 µm) or the electrostatic separation of granular particles
(size > 100 µm) [1-2].
This thesis aims to develop new applications where the electric forces allow an efficient manipulation
of particles with intermediate sizes between 1 and 100 µm. These applications include solar panels
cleaning, for which an electrostatic process would significantly reduce the cost of maintenance
compared to conventional methods (washing, brushing, vibration, etc ...).
The principle of an electrostatic cleaning system consists to apply electric forces (Coulomb and
dielectrophoretic forces) directly on the particles to overcome adhesion and gravitational forces. This
process requires the implementation of a high voltage power supply and several electrodes to create
an electric field, that vary in space and time, to manipulate particles deposited on a dielectric surface
[3-4].
Thesis Plan
Thesis work, mainly experimental, will be divided into several parts:
(1) Experimental modelling of the key parameters involved in an electrostatic cleaning system.
(2) Analysis of the electrodynamic phenomena induced by a non-uniform electric field. The use of
optical techniques of very high spatial and temporal resolutions (high speed imaging, time-resolved
PIV, ...) is programmed during this phase of study.
(3) Electrical and geometrical optimization of the system and application to solar panels cleaning.
