KU Leuven is routinely ranked near the top of innovative universities in the world, and was recently rated as the most innovative in Europe by Reuters (https: // nieuws.kuleuven.be/en/content/2019/four-years-in-a-row-ku-leuven- once-again-tops-reuters-ranking-of-europes-most-innovative-universities). As a member of this vibrant university, you will have the opportunity to not only engage in cutting-edge research, but also to hone skills that can be leveraged for future employment in industry, academia, or your own entrepreneurial pursuits. One of the great challenges for the future is to realize an environmentally friendly and affordable energy supply. Partly as a result of the higher share of renewable energy, the supply side is characterized by distributed and intermittent electrical and thermal power generation. Flexibility on the supply and demand side, including energy storage and energy conversion between different energy carriers plays a role here. In this context, the Applied Mechanics and Energy Conversion division (TME) has the ambition to develop innovative solutions for a sustainable energy supply in a wide academic collaboration. The TME division has the goal, based on its core experience around experimental techniques, modeling, integration and optimization of energy systems, to play a pioneering role in both research and education. It aims for a multiscale integration of micro-components to macro- energy systems and also does this in collaboration with academic partners, research institutions and industry.

Project

The principal motivation behind this project is the success of the Belgian partner at the World Solar Challenge (WSC). The aim of this competition is to drive across the Australian desert from Darwin to Adelaide (3021 km) as fast as possible using only solar energy. It is a very prestigious race (considered as the world championship), where student teams from top universities in the world participate, like Stanford, TU Delft, etc. In 2019, the team of KU Leuven won this competition for the first time in its history. The race was mainly won because of the aerodynamic design of the car as air resistance forces account for more than 70% of the power consumption at cruising speed. The aerodynamic resistance of the current car is so low that further decrease requires a giant leap in knowledge: beyond the state-of-the- art techniques for drag reduction need to be considered which require much more research before practical implementation. Therefore, the main objective of this PhDl is to develop a methodology to reduce the drag force of streamlined bodies using micro vortex generators (MVGs). MVGs are widely used to postpone separation (e.g. on airplane wings and cars), but to the applicants' knowledge, they have not been applied to delay laminar to turbulent transition on 3D streamlined bodies. If these MVGs are placed on the right location, a further reduction of the drag force in the order of 5% is expected, based on literature studies for other simple flow topologies. The methodology developed in this PhD will be directly validated on the new solar car design to secure the leading position of KU Leuven. After validation, the findings of this project can also be applied to a great number of other applications involving external flows, like wind turbine blades, sport aerodynamics, turbomachinery, aviation, etc. In all the mentioned applications, savings in drag force translate into financial savings and pollutant emission reduction, or in sports into glory.
