Rotor inlet blade angle [deg] 54 Rotor exit blade angle [deg] −45 Number of rotor blades [–] 15 Number of stator vanes [–] 17 However, due to the limitation of the dynamometer, the engine was not running at full load. In fact, the engine could only provide a torque of 450 ...
The map of Fig. 1 is the basic engine maps to be modi?ed recovering the exhaust heat and the coolant heat with a Rankine cycle system. The map presents the ratio of engine crankshaft power/fuel energy ?ow rate, basically the brake ef?ciency of the engine, and the brake-speci?c fuel...
Introduction A great amount of researcher attention has been focused on exploiting or recovering low-grade heat energy using the organic Rankine cycle (ORC), which has potential in using low-grade heat energy (approximately 100–150 ◦C). This grade of heat energy is very common in nature ...
[2], waste heat recovery [3] and the production of electricity through the utilization of solar thermal energy, due to its suitability for operation at small power capacities and relatively low temperatures below 300 °C, in which the conventional steam-Rankine cycle is technically infeasible or ...
For cyclic siloxanes, Angelino [17] gives a similar value of 400 ˝C. Dvornic [18,19] investigates extensively thermal properties of polysiloxanes, however, he does not give quantitative results for the degradation temperature of MM. To attain such results, different methodologies concerning ...
Hence, the optimal cycle configuration strongly depends on the value of reinjection temperature limit. Based on the survey work [20] on 26 geothermal brine power plants around the world, the reinjection temperature limit varies from 50 ◦C to 100 ◦C in practice. Despite several pioneering ...
The present work focuses on the techno-economic assessment and multi-objective genetic algorithm optimization of small-scale (40 kWth input), solar Organic Rankine Cycle (ORC) systems driven by medium-to-high temperature (up to 210 °C) parabolic dish (PDC) and trough (PTC) collectors. The ...
It ranges usually between 50 and 70% depending on the size of the plant and its complexity. Figure 2 shows the severe impact of the efficiency factor on the power-to-power efficiency for the given setup. A temperature level of the waste heat source of 80 ◦C and an ambient temperature...
