Study Notes
Sustainable Mobility Lecture Notes
- Sustainable Mobility: A presentation on sustainable transportation, focusing on the sustainability deficits in current transport systems.
- Presented by: Thomas Hamacher, Thushara Addanki, and Andrea Cadavid at the Technical University of Munich (TUM).
- Date: October 24, 2024
Sustainability Deficits of Transport
- Current transport systems are not sustainable, primarily due to high energy requirements.
Energy Requirements
- Energy(E) = Integral of F.ds
- E = energy in Newton-meters (Nm)
- F = force in Newtons (N)
- s = distance or path in meters (m)
Rolling Resistance
- Froll = mcar ⋅ g ⋅ froll ⋅ cos α
- Froll = rolling force in Newtons (N)
- mcar = mass of the car in kilograms (kg)
- g = acceleration due to gravity (m/s²)
- froll = rolling resistance coefficient
- α = gradient angle
Gradient Resistance
- Fgrad = mcar ⋅ g ⋅ sin α
- Fgrad = gradient force in Newtons (N)
- mcar = mass of the car in kilograms (kg)
- g = acceleration due to gravity (m/s²)
- α = gradient angle
Air Resistance
- Fair =½ ⋅ ρair ⋅ Cdrag ⋅ A ⋅ vrel²
- Fair = drag force in Newtons (N)
- ρair = density of the fluid (air) in kilograms per cubic meter (kg/m³)
- Cdrag = drag coefficient
- A = cross-sectional area (m²)
- vrel = relative speed (m/s)
Acceleration Resistance
- Fac = mcar ⋅ a
- Fac = acceleration force in Newtons (N)
- mcar = mass of the car in kilograms (kg)
- a = acceleration in meters per second squared (m/s²)
Determination of energy and fuel requirements
- Pdriving = Fdriving ⋅ vcar
- Edriving = Fdriving ⋅ vcar⋅ t = Pdriving⋅ t
- Driving resistance, driving power, driving energy, time of travel
- Important parameters when evaluating efficiency of energy demand for transport
