Renewable Rescources Engineering

Module description:

valid for matriculations after 2012

Lecturers:

• Prof. Dr.-Ing. Frank Beneke

• Prof. Dr.-Ing. Robert Pietzsch

Qualification aim:

• The students should get an founded overview of the recent utilization possibilities of renewable resources and renewable energies

• The essential knowledges and terms will be teached at an ready-to-use level

• Students should know different types of resources and their usage

• They should understand the energy conversions, material transformations and the technologies and components

• They should be able to analyze independently simple energy conversions by using thermophysical models and methods, for instance the calculation of power output of an hydropower plant, if the mass flow rate and the altitude difference are given

• Most of the theoretical explanations are accompanied by exercises during which examples are calculated

Content:

• fundamentals of thermodynamics of energy transformations: state quantities, flow rates, balance equations, kinds of energy, entropy, thermodynamical system as fundamental physical model

• fundamentals of renewable resources: types, availability, utilization, demands, conversion

• solar technology:

• photovoltaics and solar heat

• types of panels

• calculation of the sunray intensity

• solar updraft towers

• cooling with solar heat (absorption coolers)

• geothermal energy

• heat pumps and heat-to-power engines (Stirling, ORC, etc.)

• wind power plants, Betz' theory, design, on-shore/off-shore types

• hydropower plants, types of turbines, Segner's wheel as basic model

• biomass: types, agriculture, harvesting and compressing technologies

• biogas: composition, properties, production technologies

• combustion of biomass and biofuels, equipment, stechiometric theory

• biofuels and biolubricants, types, conversion technologies

• materials for industrial applications: biopolymers
