Hot-wire anemometry (HWA) is a measurement technique which allows for the investigation of highly fluctuating flows. It has been widely used for turbulence studies including turbomachinery flow analysis, but relatively little is reported regarding it

Organic Rankine Cycle (ORC) systems offer a suitable technique to achieve reduced energy consumption. However, experimental work is largely lacking, and there is an overweight in theoretical work. For this reason, the computation of dense gas flows s

Numerical Verification of the Thermodynamic Determination of the Hydraulic Efficiency of Radial Fans

Volume 7: Fluids Engineering.
For fans without cooling it is possible to determine the hydraulic efficiency measuring the pressure and the temperature rise through the fan. The shaft work can be determined according applying the first law of thermodynamics for an open system. Wit

A novel thermal measurement approach is presented for the determination of fan efficiencies. This approach is not resting on a simple direct measurement of the occurring temperature difference but on a system identification based on the transient tim
