SUMMARY:Thermodynamic Simulation of a Continuous Closed Loop Heated Micro-T
 urbine Test Facility
DESCRIPTION:Lecturer:Oleg Isaev\n Faculty:Department of Aerospace Engineeri
 ng\n Institute:Technion – Israel Institute of Technology\n Location:Clas
 sroom 165\, ground floor\, Library\, Aerospace Eng.\n Zoom: \n Abstract: \
 n Details: \n This incremental development project is focused around a ver
 satile continuously-running high-speed micro gas turbine research facility
 \, which is capable of matching full engine similarity conditions includin
 g pressure loading (synonymous with Mach number)\, rotational speed\, Reyn
 olds number\, as well as blade to gas temperature ratios. Towards predicti
 ng the aerodynamic and thermal conditions created on the test article\, th
 e current work describes the thermodynamic steady-state simulation of the 
 closed-loop system that consists of a compressor\, a pressure vessel\, an 
 electric heater\, a test turbine\, a dynamometer\, pressure drop valves an
 d an aftercooler. These subcomponents have inter-dependent performance par
 ameters. Based on an explicit time-marching algorithm\, virtual experiment
 s are conducted in the system model to map the performance of the micro tu
 rbine as it is influenced by the independent control parameters (rotationa
 l speed of the compressor\, rotational speed of the dynamometer\, power su
 pplied to the heating element\, and the total mass of air in the system). 
 Along these lines\, different aspects of turbine testing\, turbomachinery 
 map scaling\, component similarity analysis\, as well as simplified analyt
 ical and numerical turbine heat transfer solutions are discussed. The tool
 s and considerations associated with this effort will facilitate future en
 deavors in this research field.
