Micro turbojets are used for propelling radio-controlled aircraft, aerial targets, and personal air vehicles. When compared to full-scale engines, they characterized by relatively low efficiency durability. In this context, the degraded performance of gas path components could lead an unacceptable reduction in overall engine performance. work, a data-driven model based on conventional artificia...

A regenerative organic Rankine cycle (RORC) is modeled and optimized for the use of waste heat recovery from a prime mover (PM). Three PMs including, a diesel engine, a gas engine, and a microturbine are selected in this study. Four refrigerants including isobutane, R123, R134a, and R245fa are selected. The nominal capacity of the PM, PM operating partial load, turbine inlet pressure, condenser...

The characterization of flow through Pelton hydro turbines allows the optimization their operation and maximization energy performance. in injector free jet area (the from outlet surface to runner bucket inlet surface) is influenced by several parameters: geometry components (nozzle spear), opening, turbine head. parameters (velocity distribution, pressure spread) are reflected efficiency. rese...
