“…Waste heat recovery is a well known technology for stationary engine operations: the discussion about WHR systems for vehicle applications has, therefore, intensified over the past years, for example [2,3,4,5,6]. The most promising in-vehicle bottoming cycle is the Rankine Cycle.…”

A significant driver for the development of future commercial vehicles is likely to be the introduction of fuel consumption related legislation in various regions around the world. The application of a waste heat recovery system to the powertrain of such vehicles is seen as a possible step, amongst many, to help them achieve the required fuel economy. In particular, the Rankine Cycle (a closed steam cycle) is often proposed as a potential means for deriving work from the engine exhaust heat.Rankine Cycle systems are already in use in off-highway applications, such as stationary engines or marine powerpacks. However, the technical and commercial viability of these systems for on-highway, principally long haul truck application is as yet unproven. Aspects such as the in-use economy benefits, the system performance density, the component robustness and all interactions with the other vehicle systems have to be evaluated. These aspects translate into new challenges for suppliers of vehicle thermal management components and modules.In this paper, the simulation the Rankine Cycle system together with the complete vehicle infrastructure using in-house developed tools, in order to predict the actual likely fuel consumption benefit, is presented. Results are shown in relation to the use of alternative system layouts for a long haul vehicle application. The validation of the simulation results is also presented.

“…Valves were employed instead of turbines so that a possible power output of 12.7 kW was estimated for the test rig. Another experimental RC-ORC system with ethanol as a working fluid in the LT-ORC was described by the automobile manufacturer BMW [17], where an additional power output of about 14% was stated. However, in a subsequent development BMW focused on a single loop ORC because of its lower complexity and size [18].…”

“…To investigate the heat recovery potential through the use of exhaust gas at rolling mill furnaces, University of Applied Sciences Saarbrücken (htw saar) has already carried out by Paulus [1]. Based on the previous study, the concrete geometry of a vapor turbine is now to be developed [2][3][4]. Each turbine needs a special design according to its parameters like mass throughput, pressures, etc.…”

Heat recovery plays an important role in increasing the efficiency of renewable energy facilities like biomass furnaces, solar power plants or biofuel combustion engines. As the overall efficiency of the facilities can be increased by recovering the energy. The available waste heat can be converted directly into mechanical energy, pressure or subsequently converted into electrical energy by coupling the expansions machine with a generator. The waste heat can be converted by Organic Rankine Cycle (ORC). Therefore, an expansion machine, e.g. a turbine is required. Also small amounts of waste heat can be recovered, if so-called micro turbines are used. Design and construction of such micro turbines always follow fixed rules. Aim of this work is to explain the rules how to design a micro turbine. Furthermore, our workflow and a software tool which follows these rules should be presented.
