Welcome!

This website presents a summary of the results developed as part of the doctoral thesis entitled "Study of the Atomization of Electrohydrodynamic Jets - Modelling, Performance and Applications", submitted for evaluation in Mechanical Engineering at the University of Beira Interior. The work was developed by Sílvio Cândido, under the supervision of José C. Páscoa. The research was supported by grant no. 2020.04517.BD from the Foundation for Science and Technology and by the Center for Mechanical and Aerospace Science and Technologies.

Overview

This work is divided into three main parts: Modelling, Performance and Applications of Electrohydrodynamic Jets.

  • Modelling

    This chapter describes in detail the different methods used to calculate the two-phase flow of electrohydrodynamic jets. It covers topics such as the Finite Volume Method (FVM), the Volume of Fluid method (VoF) and Lagrangian Particle Tracking (LPT).

  • Performance

    The numerical model is extensively tested under different operating regimes, including axisymmetric jets, the development of three-dimensional instabilities and plume formation.

  • Applications

    In this chapter, the numerical model is used in two proposed applications. The first concerns the use of POD/DMD reduced-order models to create digital twins of EHD jets. The second investigates an acceleration grid for application in colloid microthrusters.
