About

Dr Togneri graduated with an MEng in Aerospace and Aeronautical Engineering from the University of Glasgow in 2007, including a final semester of study at Technische Universität München. He obtained a doctorate from the School of Mathematics in Cardiff University for his work on the development of instabilities in turbulent boundary layers.

Having started his career at Swansea University on the simulation of tidal stream turbines, he has investigated and published on a range of problems in the field of tidal stream energy, including measurement of turbulence, device reliability, and maintenance strategies.

Areas Of Expertise

Taught Modules

EG-138 Introduction to Mechatronics

This is a practical module introducing students to fundamental engineering skills including work in the laboratory, basic programming and groupwork in a design challenge. Engineering is more than understanding technical design, it is often the social, environmental and economic context underpinning engineering solutions that determine success or failure. The design challenge/ hackathon will allow you to engage with a real world engineering problem
EG-161 Thermodynamics 1

The aim of the module is to give an introduction to the laws of thermodynamics and the relevant properties, thus providing an appreciation of energy conversion processes for thermodynamic systems. Topics covered are heat and work, properties of pure substances, liquids, gases and vapours, the first and second laws of thermodynamics. The module will focus on practical problem solving of steady flow systems using conservation of energy equation applied to ideal refrigeration systems and the ideal gas turbine engine extended to ideal jet engine analysis.
EGA130 Thermofluids

This Thermofluids module will encompass theory of both Thermodynamics and Fluid Mechanics. Thermodynamics is about how heat and work relate to the energy content of a system; and Fluid Mechanics is the study of energy and forces in a fluid.
EGA334 Mechanical Engineering Design 3

This module demonstrates the outcomes of three years of learning and applies multiple skills to a design project. The project will show that students can manage and deliver a design task, as a team, through all stages of the design process. Students should progress from specification to concept design, undertake analysis (using computer tools as appropriate) and produce a design report and assembly drawings.
