Abstract

A wind turbine can act as an energy recovery device (ERS) in a comparable way to brakes (regenerative braking). When the velocity of a vehicle changes, the amount of energy related to it also changes. When its velocity decreases, the energy tends to dissipate. Over time, this dissipated energy has been ignored. For example, during the braking process, the kinetic energy of the vehicle was converted into heat. In recent years, society’s greater awareness of climate change, pollution, and environmental issues has led to a great deal of interest in developing energy recovery systems. It allows the recovery of kinetic energy from braking (KERS), resulting in consumption reductions (efficiency gains) of up to 45%. The usefulness of installing a wind turbine as an energy recovery device is analysed, evaluating the savings that can be achieved with its two possible working modes: as an energy recovery device and as a system for utilizing aerodynamic force. The wind turbine has a horizontal axis and a diameter of 50 cm and is installed on the front of a vehicle. This vehicle will undergo three particular driving schemes, which will operate under different experimental conditions and operational parameters characterized by speeds, accelerations, stops, and driving time. The results clearly show the advantages of using the proposed technology.

Highlights

Internal combustion engine vehicles are affected by two major problems, which have become worse over time: the scarcity of fossil fuels and the consequences of the associated pollution for the environment and for human health.this type of vehicle does not ensure sustainable transport in the medium and long term.The development of renewable energy systems has attracted the interest of both academics and governments

Introduction

Internal combustion engine vehicles are affected by two major problems, which have become worse over time: the scarcity of fossil fuels and the consequences of the associated pollution for the environment and for human health. This type of vehicle does not ensure sustainable transport in the medium and long term. The use of wind energy applied to motor vehicles has important implications for environmentally friendly sustainable development It is in line with the 2015 Paris Agreement [1], providing significant support for renewable energy, and with the European Union’s 2030 Climate and Energy Framework [2]
